Cap Rate in Canada: What It Is and What It Tells You
Cap rate is the most-used metric for comparing Canadian investment properties. Learn how to calculate it and what it reveals about risk and return.
Cap rate (capitalization rate) is the go-to metric for comparing investment properties — but it's often misunderstood, misapplied, or calculated incorrectly. Here's a clear explanation of what it measures and how to use it in a Canadian context.
The Formula
Cap Rate = Net Operating Income (NOI) ÷ Property Value × 100
NOI = Gross rental income − all operating expenses (excluding mortgage payments and income tax)
The mortgage is excluded intentionally — cap rate measures the unlevered return on the asset itself, independent of how it's financed. This makes it useful for comparing properties regardless of down payment or mortgage rate.
A Working Example
- Annual gross rent: $36,000
- Operating expenses (taxes, insurance, management, maintenance, vacancy): $10,800
- NOI: $25,200
- Purchase price: $600,000
- Cap Rate: 25,200 ÷ 600,000 = 4.2%
What the Cap Rate Tells You
Higher cap rate = higher income relative to price = typically indicates higher risk (older building, lower-demand area, higher vacancy) or a motivated seller
Lower cap rate = lower income relative to price = typically indicates a premium asset in a high-demand area with low vacancy risk (think Toronto condo vs. small-town apartment building)
In major Canadian urban markets, cap rates for residential properties typically range from 3%–5%. In secondary markets, 5%–8% is more common.
What the Cap Rate Doesn't Tell You
- Financing costs — A 4% cap rate with a 6% mortgage rate means you're losing money on a levered basis
- Appreciation — Cap rate is a snapshot, not a growth forecast. Many Toronto investors accept a 3% cap rate expecting 5%+ annual appreciation
- Vacancy risk — How well a property performs with 10% vacancy vs. 2% vacancy changes the real return
- Capex cycle — A property with a new roof and HVAC has different risk than one with systems at end of life
Cap Rate vs. Cash-on-Cash Return
Cap rate ignores financing. Cash-on-cash return includes your mortgage payment and measures actual return on the cash invested. Use both: cap rate to compare properties as assets, cash-on-cash to evaluate the deal given your specific financing.
