Canada is adding more rental units than at almost any point in the country’s history, and that could become one of the biggest housing stories for Ontario buyers, renters, investors, and homeowners over the next few years. According to CMHC, Canada’s housing starts increased in 2025, driven by record rental construction and more “missing middle” housing. CMHC also reported that Canada recorded 259,028 total housing starts in 2025, the fifth-highest annual total on record.
But here is the important part:
More rental units does not automatically mean homes become cheap overnight.
It may help rents cool down. It may give tenants more choices. It may reduce pressure on some buyers. But for people trying to buy a home in Bradford, Barrie, Newmarket, Vaughan, Pickering, Oshawa, Aurora, the GTA, or anywhere in Ontario, mortgage approval still comes down to income, credit score, down payment, debt, mortgage rates, and the mortgage stress test.
This blog breaks down what Canada’s rental construction boom really means — and how buyers can use this shift to make smarter mortgage decisions.
Yes. Canada is seeing record rental construction. CMHC reported that 2025 housing starts rose 6%, largely driven by record rental apartment construction and more missing middle housing. This means more rental supply is being built, but affordability still depends on interest rates, income growth, population growth, and mortgage qualification rules.
Canada has been facing a major housing shortage for years. Population growth, immigration, high construction costs, high interest rates, zoning issues, labour shortages, and slow approvals all created pressure on housing.
For many years, Canada did not build enough homes for the number of people who needed them.
Now, a major shift is happening.
Instead of only building condos and detached homes for ownership, more builders and developers are focusing on rental apartments, purpose-built rentals, multiplexes, low-rise apartments, row homes, stacked townhouses, and other missing middle housing.
CMHC’s Spring 2026 Housing Supply Report stated that Canada’s housing starts rose 6% in 2025 and that the improvement was driven by record rental and missing middle construction. However, CMHC also warned that ownership supply is under pressure because condo presales have weakened and unsold inventory has increased.
That means Canada is building more rental housing, but the ownership market is still dealing with challenges.
In simple words:
Canada may be building more places to rent, but not necessarily enough homes people can afford to buy.
There are several reasons rental construction is growing faster than ownership housing.
When rents rise too quickly, governments and developers start paying more attention to rental supply.
More rental units can help create:
CMHC’s 2025 Rental Market Report showed that the average vacancy rate for purpose-built rental apartments rose to 3.1%, up from 2.2% in 2024, meaning rental supply helped soften market conditions.
Federal, provincial, and municipal governments are trying to encourage more rental housing through financing programs, housing funds, zoning reforms, and faster approval processes.
The goal is simple: build more housing faster.
Rental apartments are often easier to support through large-scale financing programs because they create long-term housing supply.
In places like Toronto and parts of the GTA, many condo projects depend on presales. When buyers stop purchasing pre-construction condos, some projects become harder to finance.
That creates a shift.
Developers may start looking at rental projects instead of ownership projects.
This matters for Ontario buyers because fewer ownership units today can mean tighter resale supply later.
Higher mortgage rates made it harder for buyers to qualify.
When fewer buyers can qualify, demand for ownership housing slows down. But people still need somewhere to live.
That supports rental demand.
For developers, rental buildings can make more sense when the ownership market is slow, especially if government financing support is available.
More rental supply can be good news for renters, especially in markets where vacancy rates have been extremely low.
When more rental units become available, renters may see:
But this does not mean rent will collapse everywhere.
Rental prices depend on local supply and demand. For example, Barrie is not the same as Vaughan. Oshawa is not the same as Newmarket. Pickering is not the same as Bradford.
Some cities may see more rental relief than others.
A renter in downtown Toronto may experience a different market than a family looking for a rental home in Bradford West Gwillimbury, Barrie, or Aurora.
This is where things get interesting.
More rental units could reduce pressure on some first-time home buyers because renting may become slightly more stable. If rents stop rising aggressively, some buyers may have more time to save their down payment, improve their credit score, and prepare for mortgage approval.
But there is another side.
If Canada builds more rental units but fewer ownership homes, detached homes, semis, townhouses, and freehold properties may remain limited.
That could make ownership even more valuable long term.
If you are trying to buy in Bradford, Barrie, Newmarket, Vaughan, Pickering, or Oshawa, the key question is not only “Are prices going up or down?”
The better question is:
Can I qualify, afford the payment, and buy the right property without overextending myself?
Mortgage affordability is based on what lenders believe you can safely carry.
Lenders usually look at:
Even if rents soften, buyers still need to qualify under lender rules.
Let’s say a first-time buyer wants to purchase a home for $700,000 in Ontario.
Possible numbers:
Even if the buyer can afford the real payment, the lender must still approve them under qualification rules.
That is why speaking with a mortgage broker before shopping is so important.
For first-time home buyers in Ontario, more rental supply can be both helpful and frustrating.
If rent growth slows, buyers may have more breathing room.
They may be able to:
If builders focus more on rental housing and less on ownership housing, future buyers may have fewer entry-level ownership options.
That could especially affect:
The market may become split.
Canada may have more rental buildings, but fewer affordable ownership opportunities.
Many buyers spend too much time watching headlines.
They ask:
These are fair questions.
But mortgage approval is personal.
Two buyers can look at the same house and have completely different outcomes.
This buyer may have multiple options.
This buyer may struggle, even if they make decent money.
That is why a mortgage broker can help structure the file before the buyer starts shopping.
Mortgage qualification depends on the lender and the borrower’s full profile.
Most lenders will review:
This can include:
A higher credit score can improve your chances of mortgage approval.
Many lenders prefer a strong credit history, especially for insured mortgages, refinances, and high-ratio purchases.
In Canada, the minimum down payment depends on the purchase price.
For many buyers, the down payment can come from:
Lenders review your debt compared to your income.
Common debts include:
The property also matters.
A lender may review:
More rental construction can help:
There are also concerns:
The real issue is balance.
Canada needs rental housing, but it also needs ownership housing.
People need places to rent, but families also need a realistic path to ownership.
If you are planning to buy in Ontario, do not just react to headlines.
Use this market shift as a planning opportunity.
A mortgage pre-approval helps you understand:
Before applying for a mortgage, try to:
A larger down payment can help reduce risk and improve affordability.
Buyers should also budget for closing costs, including:
Even if your actual mortgage rate is lower, lenders may qualify you using a higher rate.
This protects lenders and borrowers, but it can reduce your buying power.
In some cases, renting may make sense for a little longer.
In other cases, buying may make sense if:
Let’s say a family is renting in Barrie for $3,000 per month.
They are considering buying a $750,000 home.
Possible ownership costs may include:
At first, owning may cost more per month than renting.
But ownership also builds equity over time.
Rent gives flexibility. Buying gives control.
The right answer depends on the family’s income, down payment, lifestyle, job stability, debt, credit score, and long-term goals.
This is why mortgage affordability should be reviewed before making a decision.
More rental construction may also affect homeowners.
If you already own a home in Ontario, you may be thinking about a refinance mortgage to:
If rental demand remains strong, some homeowners may consider creating legal secondary suites. This can potentially help with affordability, but it must be done properly with permits, zoning, insurance, and lender approval.
A refinance can be powerful, but it should be structured carefully.
The goal is not just to access money.
The goal is to improve your financial position.
Canada is seeing record rental construction. CMHC reported that 2025 housing starts increased and were driven by record rental apartment construction and more missing middle housing. This is one of the strongest rental construction periods in Canadian housing history.
More rental units can help slow rent growth, especially when supply catches up with demand. CMHC reported that Canada’s purpose-built rental vacancy rate rose to 3.1% in 2025, up from 2.2% in 2024. However, rent changes depend on the city, unit type, immigration, income, and local supply.
It depends on your financial situation. Renting may be better if you need flexibility, have a small down payment, or are still improving credit. Buying may be better if you have stable income, strong mortgage approval, enough savings, and plan to stay long term.
Many lenders prefer stronger credit, especially for insured mortgages and competitive rates. A higher credit score can improve approval chances, but lenders also look at income, down payment, debt, employment, and the property itself.
The minimum down payment depends on the purchase price. Buyers should also budget for closing costs such as land transfer tax, legal fees, title insurance, inspection, appraisal, and moving expenses. A mortgage broker can calculate the exact down payment needed for your situation.
Canada adding more rental units is a major housing shift.
It can help renters. It can reduce pressure in some markets. It can give people more options. It may even help inflation and affordability over time.
But for Ontario home buyers, the bigger lesson is this:
Do not wait for the market to become perfect.
The buyers who win are usually the ones who prepare early.
They understand their mortgage approval. They improve their credit score. They save their down payment. They reduce debt. They compare mortgage rates. They get advice before they fall in love with a property.
Whether you are buying your first home, refinancing your mortgage, moving from renting to owning, or trying to understand what you can afford in Bradford, Barrie, Newmarket, Vaughan, Pickering, Oshawa, Aurora, the GTA, Ontario, or anywhere in Canada, the right mortgage strategy matters.
