The Offer-to-Keys Timeline

What actually happens between signing the offer and picking up the keys, and the paperwork at each step. For province-specific steps, see our Buy a Home guide.

  1. 1

    Make a Conditional Offer

    Day 0

    Submit a written offer through your agent (or directly in a private sale). A conditional offer protects you: standard conditions are financing, home inspection, and a status certificate review if buying a condo.

    Documents / Actions

    • ›Signed Agreement of Purchase and Sale (Ontario: OREA form; BC: Contract of Purchase and Sale; other provinces vary)
    • ›Mortgage pre-approval letter (shows seller you're serious)
    • ›Personal cheque for deposit (in trust, typically due on condition removal, not signing)
  2. 2

    Conditions Period

    Days 1–10 (typically 5–10 business days)

    Get your financing confirmed in writing, complete your home inspection, and (if condo) review the status certificate package from the condo corporation.

    Documents / Actions

    • ›Mortgage commitment letter from your lender (written confirmation of financing)
    • ›Home inspection report (book independently, choose a certified inspector, not one referred by your agent)
    • ›Status certificate + reserve fund study + meeting minutes (condo only, have a lawyer review)
    • ›Title search (your lawyer orders, confirms clear title, identifies liens, easements, encumbrances)
  3. 3

    Remove Conditions: Offer Goes Firm

    End of conditions period

    Sign a waiver removing your conditions. The deal is now firm and legally binding. Pay your deposit.

    Documents / Actions

    • ›Signed condition waiver (or amendment if negotiating repairs)
    • ›Deposit: bank draft or certified cheque payable to seller's brokerage in trust (wire transfer increasingly common). BCFSA, BC's regulator, publishes that five to 10 per cent of the purchase price is typical and that any amount can be negotiated between a buyer and seller; there is no national figure.
    • ›Deposit receipt from the brokerage
  4. 4

    Prepare with Your Lawyer / Notary

    2–4 weeks before closing

    Hire a real estate lawyer (all provinces) or notary (Quebec). They handle the title search, mortgage registration, and fund disbursement. Arrange title insurance and home insurance, your lender requires both.

    Documents / Actions

    • ›Government-issued photo ID (×2, passport + driver's licence is ideal)
    • ›90-day bank account statements showing down-payment source (every deposit that isn't regular pay needs explanation)
    • ›Gift letter if any of the down payment is a gift (signed by donor; confirms no repayment expected)
    • ›FHSA/RRSP HBP withdrawal confirmation (if using, see the incentives module above)
    • ›Title insurance commitment (lender's + owner's, your lawyer arranges)
    • ›Home insurance binder or policy (must be in effect on closing day)
    • ›Mortgage instructions from your lender to your lawyer
  5. 5

    Closing Day

    Your agreed closing date

    Your lawyer registers the transfer of title and mortgage on title, then releases funds to the seller's lawyer. You pay the balance of down payment plus all closing costs (LTT, legal fees, PST on CMHC if applicable, property-tax and utility adjustments). Once registration is confirmed, typically early afternoon, the keys are released.

    Documents / Actions

    • ›Direction re Funds (authorizes your lawyer to disburse the mortgage proceeds)
    • ›Statement of Adjustments (itemizes all debits and credits, property tax prepaid by seller, unused utilities, condo-fee adjustments, etc.)
    • ›Signed mortgage documents
    • ›Certified cheque or bank wire for closing balance (lawyer confirms exact amount a few days before)
    • ›Keys, garage openers, alarm codes, and appliance manuals from the seller
  6. 6

    After Closing: Admin

    First few weeks

    You own it: now set up the admin. Update your address everywhere, get utilities in your name, and register your property-tax account (or confirm your lender is collecting it with your mortgage payment).

    Documents / Actions

    • ›Certificate of possession (from your lawyer, proof you're now on title)
    • ›Property tax account setup with your municipality (or confirm lender tax account)
    • ›Utility account transfers: hydro, natural gas, water
    • ›Address change: driver's licence, health card, CRA, bank, employer, insurance

Province-specific steps

Closing practices, deposit rules, and required forms vary by province. See our Buy a Home step-by-step guide for province-specific details including Quebec's notary requirement, BC's Property Transfer Tax, and Nova Scotia's deed transfer tax.

How lenders calculate what you can afford

Canadian mortgage lenders use two debt-service ratios to set the ceiling on your borrowing:

Gross Debt Service (GDS): must be ≤ 39%

GDS = (mortgage P+I + property tax + heat + ½ condo fees) ÷ gross monthly income

The property-tax and heat figures are estimates: the calculator pre-fills typical amounts that you should adjust to your target area.

Total Debt Service (TDS): must be ≤ 44%

TDS = GDS numerator + all other monthly debt payments

Car loans, student loans, credit card minimums, lines of credit, everything that shows on a credit bureau. Do not include the mortgage you're applying for.

The binding constraint is whichever ratio produces the lower maximum payment. Most buyers without existing debt are bound by GDS; those with car or student loans are often bound by TDS.

The stress test

On top of the ratios, OSFI's stress test (Guideline B-20) requires lenders to qualify you at a rate higher than your contract rate. The qualifying rate is the greater of:

  • Your contract rate plus 2 percentage points, or
  • The 5.25% floor (in effect since June 2021, OSFI)

If your lender offers 5.00%, you qualify at 7.00%. This is why the maximum price from an affordability calculator is always lower than what a simple payment calculator suggests at the contract rate alone.

Worked example

$120,000 income, $100,000 down, 5.00% rate, 25-yr amortization, $350/mo property tax, $150/mo heat:

  • Qualifying rate = max(5.00% + 2%, 5.25%) = 7.00%
  • GDS budget = 0.39 × ($120k/12) − $350 − $150 = $3,900 − $500 = $3,400/mo
  • Max total loan at 7.00% / 25yr ≈ $487,000 (principal + CMHC)
  • Loan base (before CMHC) ≈ $487,000 ÷ 1.028 ≈ $473,000 (CMHC ~2.80% at this LTV)
  • Max price ≈ $473,000 + $100,000 = $572,000 (rounded to nearest $1,000)

How Canadian mortgage math works

Unlike US mortgages (monthly compounding), Canadian law requires fixed-rate mortgages to use semi-annual compounding. The effective monthly rate is:

i = (1 + r / 2)1/6 − 1

where r is the annual nominal rate. At 5.00%, this gives i = 0.4124% per month, slightly lower than 5/12 = 0.4167%. The difference compounds over 25 years and results in meaningfully different totals from US-style calculations.

Prepayments

Every dollar of prepayment reduces your outstanding balance, which reduces every future interest charge. Because interest is calculated on the remaining balance, prepayments made early in the amortization have the most impact. The prepayment explorer shows you exactly how much you'd save in total interest and how many months sooner you'd be mortgage-free.

Most closed mortgages allow annual lump-sum prepayments of 10–20% of the original principal without penalty. Check your mortgage agreement for your specific privilege.

Worked example: $500,000 at 5.00% / 25 years monthly

  • Effective monthly rate: (1 + 0.05/2)1/6 − 1 = 0.41240% (not 0.41667%)
  • Monthly payment: ≈ $2,908/mo
  • Total paid: $2,908 × 300 = $872,400
  • Total interest: $872,400 − $500,000 = $372,400
  • Adding $200/mo extra → saves ≈ $53,000 in interest, finishes ≈ 4 years early

What closing costs should I budget for?

Many first-time buyers underestimate closing costs. Beyond the down payment, plan for:

Land Transfer Tax

Every province except Alberta, Saskatchewan, and NL charges an LTT on the purchase. Ontario at $700k = $10,475 gross; first-time buyers get a $4,000 rebate → $6,475 net. Toronto buyers pay an additional MLTT (same amount) minus a $4,475 rebate.

PST on CMHC Premium

If your down payment is under 20% and you're in Ontario, Quebec, or Saskatchewan, you pay provincial sales tax on the CMHC premium IN CASH at closing. It cannot be added to the mortgage. At $500k with 10% down: CMHC = $13,950 × 8% = $1,116 cash (Ontario).

Legal / Notary Fees

A real estate lawyer or notary handles the title search, mortgage registration, and fund transfer. Budget $1,200–$2,500 depending on province and complexity. Quebec requires a notary.

Title Insurance

Lender title insurance protects the lender against title defects; owner's title insurance protects you. Together typically $250–$600. Most lenders require it.

Home Inspection

A qualified inspector checks the structure, electrical, plumbing, roof, and HVAC. Budget $400–$700 for resale. New builds may be covered by builder warranties (Tarion in Ontario; BC New Home Warranty), but an independent inspection is still worthwhile.

Adjustments

If the seller has prepaid property tax or condo fees, you reimburse them for the portion that covers after your closing date. Your lawyer calculates this on the Statement of Adjustments.

Worked example: ON first-time buyer, $700,000 resale, 20% down

  • Down payment: 20% × $700,000 = $140,000
  • Ontario LTT: $10,475 gross − $4,000 first-time rebate = $6,475 net
  • PST on CMHC: $0 (20% down → no CMHC)
  • GST rebate: $0 (resale, GST does not apply)
  • Legal ($1,500) + title ($400) + inspection ($500) = $2,400 estimates
  • Total cash to close: ≈ $148,875 (before adjustments)

Pre-Approval Readiness Checklist

General readiness checklist, not financial advice. Requirements vary by lender, employment type, and loan program. Always verify with a licensed mortgage professional.

Credit & Financial History

  • Know your credit score: most lenders want 680+ for best rates; 600+ is a common minimum. Check free via Borrowell or Credit Karma (Canada).
  • Obtain your credit report (free via Equifax and TransUnion Canada once per year) and dispute any errors before applying.
  • Avoid opening new credit accounts or making large purchases on credit in the 90 days before applying.
  • Pay down revolving credit (credit cards, lines of credit) to below 30–35% utilization before applying.

Income & Employment

  • T4(s) and Notice of Assessment (NOA) from the last 2 tax years.
  • Recent pay stubs (last 30–90 days) showing regular employment income.
  • Letter of employment on company letterhead: job title, employment type (full-time/part-time), start date, salary or hourly rate.
  • Self-employed / commission: 2 years of T1 Generals + business financials; lenders use a 2-year income average.
  • Income from rental property: T776 Rental Income Schedule + signed lease agreements.

Down Payment & Assets

  • 90-day bank account history for ALL accounts showing the down payment funds, the full 90-day history, not just a current balance.
  • Every large deposit (anything outside regular payroll) needs a paper trail: employment bonus letter, proceeds from sale of an asset (with the sale agreement), FHSA/RRSP withdrawal confirmation.
  • If using an RRSP HBP withdrawal: confirm your RRSP has been open for 90+ days before withdrawal; obtain the CRA T1028 form.
  • If using an FHSA: confirm you qualify (18+, first-time buyer per the 4-year lookback); get the withdrawal confirmation.
  • Investment account statements (last 90 days) if using non-registered funds.

Gift Funds (if applicable)

  • Signed gift letter from the donor: must state the full amount, the relationship to you, and that no repayment is expected.
  • Proof the gift funds have been deposited into your account (bank statement showing receipt).
  • Some lenders require a bank statement or letter from the donor showing they had the funds to give.
  • Note: some lenders and CMHC require that a portion of the minimum down payment come from your own resources, confirm with your lender.

Debts & Liabilities

  • List all monthly debt payments: car loans, student loans, credit card minimums, personal loans, lines of credit, child/spousal support obligations.
  • These feed directly into the TDS ratio. Do NOT omit any, the lender will pull your credit bureau and see everything.
  • If you co-signed for someone else's loan, that payment may be counted as your liability, confirm with the lender.

Identity Documents

  • Two pieces of government-issued ID; at least one must have your photo.
  • Accepted primary: Canadian passport, driver's licence, provincial ID card, Permanent Resident card.
  • Accepted secondary: SIN card (note: lenders record your SIN for credit bureau purposes), birth certificate, health card (most provinces).
  • Must match the name on your mortgage application exactly.

Understanding your true monthly cost of ownership

Your mortgage payment is only the beginning. A realistic monthly housing budget includes property tax, utilities, insurance, water and sewer, all of which vary significantly by province and property type. Underestimating these costs is one of the most common financial mistakes new homeowners make.

Property Tax

Charged by your municipality as a percentage of your home's assessed value. Assessment practices vary widely, the assessed value can be well below or close to market value depending on the province. The rate in Module 6 is applied to the purchase price as a starting estimate, but your actual bill depends on your specific property's assessed value. Look up your municipality's current residential mill rate for accuracy.

Electricity

Provincial rates vary dramatically, from ~$95/mo in Quebec (low-cost hydro) to ~$231/mo in Alberta (deregulated market). The defaults come from the Hydro-Québec annual electricity rate comparison, which uses a standardized 1,000 kWh/month consumption for comparability. Your actual usage will depend on home size, appliances, EV charging, and heating system.

Heating

For provinces using natural gas heat (ON, BC, AB, SK, MB), budget ~$97/mo year-averaged after the federal carbon charge was removed April 1, 2025. For heating oil (NS, PE), budget ~$270/mo, but oil is volatile and can swing significantly with crude prices. For provinces where electric heat is dominant (QC, NB, NL), the heating cost is already inside the electricity estimate, adding a separate heating line would double-count it.

Home Insurance

Budget $100–$145/mo as a starting point. Get real quotes, rates vary significantly by home age, construction type, location, claims history, and deductible. The defaults are provincial aggregates from Ratehub/PolicyMe 2026 data.

Condo / Strata Fees

If you're buying a condo, strata, or townhouse, monthly maintenance fees cover building insurance, common area upkeep, reserve fund contributions, and sometimes utilities. These fees are not estimable without your specific building, check the strata documents before making an offer.

Worked example: ON gas-heat, $700,000 purchase, 20% down, 5.74% / 25yr

  • Mortgage payment: ~$3,497/mo ($560k loan at 5.74%, Canadian semi-annual compounding)
  • Property tax: 0.72% × $700k ÷ 12 = $420/mo (Toronto estimate)
  • Electricity: $179/mo (ON average, 1,000 kWh)
  • Gas heating: $97/mo (year-averaged, carbon charge removed)
  • Water & sewer: $85/mo
  • Home insurance: $145/mo (ON estimate)
  • Total monthly cost: ~$4,423/mo (before condo fees or custom expenses)

First-time buyer incentives in Canada (2025–2026)

Canada offers several meaningful incentives for first-time buyers. The landscape changed significantly in 2024–2025: the CMHC Shared Equity Mortgage (First-Time Home Buyer Incentive) was discontinued, while the FHSA was expanded and a new GST rebate for new builds was introduced.

FTHB GST Rebate: up to $50,000 (NEW BUILDS ONLY)

Announced March 2025, in force for purchase agreements on or after March 20, 2025. First-time buyers of new homes get back up to 100% of the federal 5% GST paid, capped at $50,000.

  • • Home value ≤ $1,000,000 → full rebate (up to $50,000)
  • • $1,000,001–$1,499,999 → linear phase-out (e.g. $1.25M → $25,000)
  • • ≥ $1,500,000 → no rebate
  • • Resale homes are ineligible: GST is not charged on resale

First Home Savings Account (FHSA): $8k/yr, $40k lifetime

Contributions are tax-deductible (reduces your income like an RRSP). Qualifying withdrawals for a first home are completely tax-free, including investment growth. Max $8,000/year ($16,000 in year 2 if you carry forward unused room), $40,000 lifetime. Can be combined with the HBP for the same purchase.

RRSP Home Buyers' Plan (HBP): up to $60,000

Withdraw up to $60,000 per person ($120,000 per couple) from your RRSP tax-free toward a first home. Repay over 15 years starting the second year after first withdrawal (for 2026+ withdrawals). The 2022–2025 window that allowed a 5-year deferral has closed.

First-Time Home Buyers' Tax Credit (HBTC): $1,500

Claim up to $10,000 on line 31270 of your tax return → 15% = $1,500 non-refundable federal tax credit. Must be claimed in the year you buy. Splittable between co-buyers (total ≤ $10,000).

Worked example: ON first-time buyer, $700,000 new build

  • GST rebate: $700,000 × 5% = $35,000 (≤ $1M → 100%)
  • Ontario LTT first-time rebate: $4,000
  • HBTC (post-purchase): $1,500 tax credit
  • Total quantifiable: $40,500, reduces cash to close by $39,000

Frequently Asked Questions

How much house can I afford in Canada?

Use the GDS/TDS ratios (39%/44%) combined with the OSFI stress test. Your maximum is determined by whichever constraint binds first. As a rule of thumb, most buyers can afford roughly 4–5× their annual income depending on their down payment and debt load.

What is the minimum down payment in Canada?

For homes up to $500,000: 5%. For $500,001–$1,499,999: 5% on the first $500k plus 10% on the remainder. For $1,500,000+: 20% (insured mortgages not available). These rules have been in effect since December 2024.

What is CMHC insurance and when do I need it?

CMHC mortgage loan insurance is required when your down payment is less than 20% and the purchase price is under $1,500,000. The premium (0.60%–4.00% of the loan) is added to your mortgage. A 30-year amortization costs an extra 0.20%. You pay provincial sales tax on the premium in cash at closing if you're in Ontario, Quebec, or Saskatchewan.

Does the stress test apply to mortgage renewals?

As of November 21, 2024, a straight switch at renewal, same loan amount and remaining amortization, no refinancing, is exempt from the stress test regardless of whether you stay with your current lender or switch to a new one. If you refinance or increase the loan amount, the stress test still applies. Credit unions and unregulated lenders may apply different rules.

Does the FTHB GST rebate apply to resale homes?

No. GST is not charged on resale homes in Canada, so the FTHB GST rebate is strictly for new builds. The tool gates this hard: if you select "resale," the rebate does not appear in your cash-to-close or incentives summary.

Can I use both the FHSA and the RRSP Home Buyers' Plan for the same purchase?

Yes. You can withdraw from both an FHSA and an RRSP (via the HBP) for the same home purchase. An FHSA withdrawal ($40k lifetime) is tax-free including growth; an HBP withdrawal ($60k per person) must be repaid over 15 years. Combined, a couple could use up to $200,000 in tax-advantaged savings toward a down payment.

What is the total monthly cost of owning a home in Canada?

Beyond the mortgage, budget for property tax (÷12), home insurance (~$100–$145/mo), electricity (~$95–$231/mo by province), heating (gas ~$97/mo; oil ~$270/mo; electric heat is captured inside the electricity estimate, not a separate charge), and water/sewer (~$85/mo). For a $700,000 home in Toronto with 20% down at current rates, total monthly costs typically run ~$4,200/mo including the mortgage. Use Module 6 above to build your own estimate.

Does electric heat get counted twice in the monthly estimate?

No: the calculator includes a double-count guard. For provinces where electricity is the primary heat source (Quebec, New Brunswick, Newfoundland), the heating line shows $0 with a note explaining it's already included in the electricity estimate. Stacking a separate heating estimate on top would overstate monthly costs. If you switch the fuel type to gas, a separate heating line appears.

How accurate is this calculator?

It uses the correct Canadian semi-annual compounding formula, current CMHC premium tiers, the official OSFI stress-test rate, and verified land transfer tax tables from provincial government sources. Utility and insurance defaults come from the Hydro-Québec 2025 rate comparison and Ratehub/PolicyMe 2026 data. It is a planning tool. Actual approval and costs depend on your specific property, lender, and usage. Always get real quotes and verify with a licensed professional.
