Whether you’re thinking about selling, refinancing, accessing home equity, or just curious — knowing your home’s current value is essential. Here are all the ways to determine what your house is worth in Canada, from free online tools to professional appraisals.
Valuation methods at a glance
| Method | Cost | Accuracy | Speed | Best For |
|---|
| Online estimator (AVM) | Free | ±5%–15% | Instant | Quick ballpark estimate |
| Municipal assessment | Free | Often below market | Already available | Understanding property tax basis |
| Comparative Market Analysis (CMA) | Free | ±3%–10% | 1–3 days | Pre-listing or general planning |

Method 1: Online home value estimators (AVMs)
Automated Valuation Models use algorithms, recent sales data, property records, and market trends to estimate your home’s value.
How AVMs work
| Data Used | What It Tells the Algorithm |
|---|
| Recent comparable sales | What similar homes sold for nearby |
| Property characteristics | Size, age, lot size, number of bedrooms/bathrooms |
| Tax assessment data | Baseline property details |
| Local market trends | Price direction and momentum |
| Listing history | Previous sale prices and listing prices |
| Tool | Coverage | Data Source | Notes |
|---|
| HouseSigma | Ontario, BC, Alberta, others | MLS sales data | Most comprehensive in Ontario; shows actual sold prices |
| Zoocasa | National | MLS and public records | Provides estimate range |
| Redfin | Major Canadian markets | MLS data | Redfin Estimate with confidence score |
| Realtor.ca | National | CREA MLS | Listing data (not sold prices in all provinces) |
| Wowa.ca | National | Public data + MLS | Neighbourhood-level estimates |
| MPAC (Ontario) | Ontario | Municipal assessment data | Assessment value, not market value |
AVM accuracy factors
| Factor | More Accurate | Less Accurate |
|---|
| Location | Urban/suburban with many sales | Rural or low-volume areas |
| Property type | Standard detached, semi, condo | Unique, custom-built, heritage homes |
| Recent sales | Many comparables in last 6 months | Few or no recent sales nearby |
| Renovations | Standard condition | Major upgrades (kitchen, additions) not in public data |
| Market conditions | Stable market | Rapidly rising or falling market |
Use AVMs as a starting point — they’re great for a quick ballpark but should not be your only source for major financial decisions.
Method 2: Municipal property assessment
Every province has a property assessment authority that determines values for property tax purposes.
Provincial assessment authorities
| Province | Authority | Assessment Cycle | Website |
|---|
| Ontario | MPAC (Municipal Property Assessment Corp) | Every 4 years (currently frozen at 2016 values) | mpac.ca |
| BC | BC Assessment | Annually (July 1 valuation date) | bcassessment.ca |
| Alberta | Municipal assessors | Annually (July 1 valuation date) | Varies by municipality |
| Quebec | Municipal evaluation roll | Every 3 years | Varies by municipality |
| Manitoba | Municipal assessment offices | Every 2 years | Varies by municipality |
| Saskatchewan | SAMA (Sask Assessment Management Agency) | Every 4 years | sama.sk.ca |
| Nova Scotia | PVSC (Property Valuation Services Corp) | Annually | pvsc.ca |
| New Brunswick | Service New Brunswick | Annually | snb.ca |
| PEI | Provincial Treasury | Annually | princeedwardisland.ca |
| Newfoundland | Municipal Assessment Agency | Varies | ma.gov.nl.ca |
Why assessment value ≠ market value
| Factor | Assessment | Market Value |
|---|
| Timing | May be 1–4 years old | Current as of today |
| Methodology | Mass appraisal (statistical models) | Individual property analysis |
| Interior condition | Rarely inspected | Considered by buyers/appraisers |
| Renovations | May not be captured | Directly impacts value |
| Market sentiment | Uses historical data | Reflects current demand |
| Purpose | Tax calculation | What a buyer would actually pay |
Ontario example: MPAC assessments have been frozen at 2016 values since 2017 (assessment updates deferred through multiple provincial decisions). A home assessed at $500,000 (2016 value) may be worth $850,000+ at current market prices.
Method 3: Comparative Market Analysis (CMA)
A CMA is a report prepared by a real estate agent that estimates your home’s value based on recent sales of similar properties.
What a CMA includes
| Component | What It Covers |
|---|
| Active listings | What competing homes are currently asking |
| Sold comparables | What similar homes actually sold for (last 3–6 months) |
| Expired/withdrawn listings | Homes that failed to sell — indicates price ceiling |
| Adjustments | Differences between your home and comps (size, condition, features) |
| Price recommendation | Suggested value range |
What makes a good comparable
| Factor | Ideal Comparable |
|---|
| Location | Same neighbourhood (within 500m–1km) |
| Property type | Same type (detached, semi, condo) |
| Size | Within 10%–15% square footage |
| Age | Within 10 years |
| Condition | Similar renovation level |
| Sale date | Sold within last 3–6 months |
| Lot size | Similar (for freehold properties) |
CMA pros and cons
| Pros | Cons |
|---|
| Free (agents provide as a service) | Agent may inflate value to win the listing |
| Considers local knowledge and nuance | Quality varies widely by agent |
| More accurate than AVMs for unique properties | Not a formal appraisal — not accepted by lenders |
| Available within 1–3 days | Subjective — different agents may give different values |
Tip: Ask 2–3 agents for CMAs and compare. If all three are within 5% of each other, you have a reliable range.
Method 4: Professional appraisal
A certified appraisal is the gold standard for home valuation. It’s the only method accepted by lenders for mortgage and equity lending decisions.
What appraisers evaluate
| Category | Specific Items |
|---|
| Exterior | Condition, construction type, roof, siding, foundation, lot grading |
| Interior | Layout, room count, condition, flooring, kitchen, bathrooms |
| Measurements | Above-grade and below-grade square footage |
| Systems | Heating, cooling, electrical, plumbing |
| Upgrades | Renovations, additions, quality of finishes |
| Comparables | 3–6 recent sales with detailed adjustments |
| Market conditions | Current supply/demand in the local market |
| Zoning | Compliance with local zoning bylaws |
Appraisal cost by property type
| Property Type | Typical Cost | Timeline |
|---|
| Standard residential (urban) | $300–$500 | 3–7 days |
| Condo | $250–$400 | 3–5 days |
| Luxury home (>$1.5M) | $500–$1,000 | 5–10 days |
| Rural property | $400–$750 | 5–10 days |
| Multi-unit (2–4 units) | $500–$1,000 | 7–14 days |

| Mortgage refinance | Yes — lender orders it |
| Home equity loan | Yes |
| HELOC application | Sometimes (some lenders accept AVM/desktop) |
| Selling your home | No (but can be helpful for pricing) |
| Divorce / separation | Yes — for equitable division |
| Estate settlement | Yes — for tax purposes |
| Property tax appeal | Recommended — supports your case |

| AACI | Appraisal Institute of Canada (AIC) | Accredited Appraiser Canadian Institute — highest designation |
| CRA | Appraisal Institute of Canada (AIC) | Canadian Residential Appraiser — residential specialist |
| P.App | AIC membership designation | Professional Appraiser (used alongside AACI or CRA) |
Method 5: Desktop and drive-by appraisals
For lower-risk lending decisions, lenders may accept a lighter-touch valuation.
| Type | What It Involves | Cost | When Used |
|---|
| Desktop appraisal | Appraiser reviews data and photos without visiting | $100–$200 | HELOCs, low-LTV refinances |
| Drive-by appraisal | Appraiser views exterior only, reviews comps | $150–$300 | Some HELOC applications |
| AVM with confidence score | Automated model with lender-grade scoring | $25–$75 | Low-risk renewals, switches |
