Understanding Vacancy Rates in Canada's Largest Rental Markets

Canada's rental market is changing. After several years of tight rental conditions, increased housing supply and slower population growth have given renters more options in many major cities. For real estate investors, these changes make understanding vacancy rates in Canada's rental market more important than ever.

A vacancy rate can help investors assess rental demand, estimate potential income, and understand how much competition they may face when attracting tenants. However, the national picture does not tell the whole story. Toronto, Vancouver, Calgary, Edmonton, and other major Canadian markets have different rental conditions, and those differences can affect investment decisions.

According to the Canada Mortgage and Housing Corporation (CMHC), Canada's purpose-built rental apartment vacancy rate increased to 3.1% in 2025, up from 2.2% in 2024. The increase reflected historically high rental construction alongside slower population and economic growth. Despite this shift, affordable rental units remained in high demand across many markets.

For real estate investors, the key is understanding what these numbers mean for individual properties and how vacancy trends can influence long-term investment performance.

What Is a Vacancy Rate, and Why Does It Matter?

The vacancy rate measures the share of rental units that are available for rent within a particular housing market or property group. A low vacancy rate generally indicates strong demand relative to available supply, while a higher rate may mean renters have more options and landlords face greater competition.

For property investors, vacancy rates matter because an empty unit generates no rental income while many ownership expenses continue. Mortgage payments, property taxes, insurance, and maintenance costs still need to be covered, even when a tenant is not paying rent.

Vacancy rates also influence rental pricing. When available units are limited, landlords may have more flexibility in setting asking rents. When vacancies increase, they may need to offer competitive pricing or move-in incentives to attract tenants.

However, vacancy rates should not be considered in isolation. Property type, neighbourhood, rental price, building condition, and unit size can all influence how quickly a property attracts tenants. A city with a rising overall vacancy rate may still have strong demand for well-maintained, reasonably priced rental housing.

Vacancy Rates Across Canada's Largest Rental Markets

CMHC's 2025 Rental Market Report shows that vacancy conditions differ significantly across major Canadian cities. In its 2026 update, CMHC also estimated that each market has a different vacancy range associated with balanced rent growth. These figures are useful context, but they are not guarantees of future performance.

In Toronto, the purpose-built apartment vacancy rate reached 3.0% in 2025. Increased rental supply and competition from investor-owned condominium apartments gave renters more options, particularly in newer, higher-priced buildings. Investors should look closely at competing units and avoid assuming that previous rental rates will remain achievable.

In Vancouver, the purpose-built vacancy rate reached 3.7%, its highest level in more than 30 years, according to CMHC. New rental construction and slower demand contributed to the increase. However, affordable rental units remained difficult to find, showing that higher overall vacancy does not necessarily mean every segment of the market has softened equally.

In Calgary, the vacancy rate reached 5.0% in 2025 as substantial new supply entered the market. This gives investors more reason to examine competition, realistic rental prices, and the time needed to find tenants. In Edmonton, the rate was 3.8%, with increased supply also contributing to softer conditions. Both markets can offer opportunities, but investors need to assess individual neighbourhoods rather than relying on population growth or past rent increases alone.

Other major markets show different patterns. Ottawa's vacancy rate reached 3.0%, while Montréal's was 2.9% and Halifax's was 2.7%. These differences reflect varying levels of rental supply, demand, and local market conditions. For investors, they reinforce the importance of researching the specific property type and neighbourhood before making a purchase.

These figures refer to purpose-built rental apartments and should not be confused with vacancy rates for rental condominiums, which can differ substantially. The full data and city-level analysis are available in CMHC's 2025 Rental Market Report.

How Investors Can Use Vacancy Rates

Understanding vacancy rates can help investors build more realistic financial projections. If a market has rising vacancies, consider allowing more time to find tenants, budgeting for periods without rental income, and using conservative rent estimates. If vacancies remain low, demand may be stronger, but that does not automatically make a property a good investment if the purchase price and operating expenses are too high.

Investors should also compare vacancy rates with rental supply, local employment, population trends, and the number of similar properties available. CMHC's 2026 Mid-Year Rental Market Update highlights that newly completed buildings and higher-priced units are experiencing more competition in several markets, while demand for more affordable rentals remains strong.

Ultimately, vacancy rates are one part of a broader investment analysis. They help explain market conditions, but property-level research is essential for estimating rental income and evaluating potential cash flow.

Make Better Decisions With Market Knowledge

Canada's rental markets are not moving in the same direction or at the same pace. Some cities are adjusting to a larger supply of available units, while affordable housing remains in short supply. Investors who understand these differences can make better-informed decisions about where to invest, how to price rentals, and how to prepare for vacancies.
