Buy vs rent guide
Rent control by province and your buy vs rent decision
Rent regulation in Canada is set by each province, so the same buy vs rent question can have a very different answer in Toronto, Vancouver or Calgary. This guide explains what a rent cap does, shows three provincial examples, and tests how much rent growth matters to the result.
Why rent rules belong in a buy vs rent comparison
Rent is the renter's largest and least certain cost over time. A buyer with a fixed-rate mortgage knows the principal and interest payment for the term. A renter knows the rent for the current lease, and then depends on what the rules allow the landlord to do next.
That is why rent growth is one of the main inputs in any buy vs rent calculation. If rent climbs quickly, owning gets a larger head start. If rent climbs slowly, the renter's savings have more time to grow and the gap narrows.
Provincial rent regulation puts a ceiling on one side of that input in some places, and no ceiling at all in others. Before you plug a rent growth number into the main calculator, it helps to know which regime you are actually in.
Three provinces, three approaches
Rent-regulation regimes differ by province, and they are revised from time to time. The table below uses only the figures we can state with confidence for 2026, and flags where you should confirm the current rule. For any other province, we do not list a cap here. Check your provincial tenancy board directly.
Notice the pattern: even where a cap exists, it usually comes with a notice period and a frequency limit, and it may not apply to every unit.
| Province | Annual increase rule | Notice and timing | Worth knowing |
|---|---|---|---|
| Ontario | Guideline of 2.1% for 2026 | 90 days' written notice; no more than once in 12 months | Units first occupied before Nov 15, 2018 are covered; newer units are exempt from the guideline |
| British Columbia | Maximum of 2.3% for 2026 | Three months' notice | Sources conflicted when we checked, so confirm the figure each year |
| Alberta | No rent-control cap | Proper written notice is still required | Check the current notice periods before relying on them |
What a cap does and does not do
A cap limits how much a landlord can raise rent on an existing tenancy. It does not mean the market rent in your city stands still. If you move, the rent on your next unit is usually set by the market, not by your old lease.
Exemptions matter too. In Ontario, newer units are outside the guideline, so a renter in a recent building may not have the same protection as a renter in an older one. Always confirm that your specific unit is covered before assuming a cap applies.
The practical effect for a long-term renter is more predictable costs while they stay put. For a renter who moves every few years, the cap matters less than the starting rent on each new lease.
- A cap applies to increases during a tenancy, not to the rent you will face if you move.
- Coverage can depend on when the unit was first occupied, the building type, or the lease.
- Notice periods and frequency limits protect against surprise increases, but they differ by province.
Testing how much rent growth matters
To see the size of the effect, we ran one illustrative household through the calculator. Suppose a $600,000 home with 20% down, a 4.5% mortgage rate, a 25-year amortization, 3.5% yearly home appreciation and 5.5% investment returns, compared with renting a similar place at $2,300 a month. Only rent growth changes between rows.
These are planning inputs for illustration, not market data. They show the shape of the effect rather than a forecast for any city.
| Annual rent growth | Approx. monthly rent in year 10 | Buyer net worth minus renter net worth after 10 years |
|---|---|---|
| 2.1% | $2,773 | +$26,539 |
| 3.0% | $3,001 | +$41,686 |
| 5.0% | $3,568 | +$77,919 |
| 7.0% | $4,228 | +$118,010 |
What this means by region
Where rent growth is capped, the renter's side of the comparison is steadier, and the break-even point tends to move later. Where there is no cap, you need to be more careful about what rent growth you assume. Using a single flat number can hide the risk that rent jumps at renewal.
A sensible approach is to run three cases: a low rent growth case that matches the cap or the recent pace in your area, a middle case, and a high case that treats rent as uncapped. If buying wins or loses in all three, the decision is not very sensitive to rent rules. If the answer flips, rent growth is a key assumption and deserves research.
Our rent growth assumptions guide explains how to pick those numbers, and the rent growth tool lets you see the effect directly.
How to check the rules where you live
Rules change, and this page cannot replace the source. Use it to frame your questions, then confirm the details with the official body in your province.
Start with your provincial tenancy board or branch and look for the current annual increase limit, the required notice, how often an increase is allowed, and which units are exempt. Keep a note of the date you checked so you know when to look again.
- Is my unit covered by the cap, or is it exempt?
- How much notice is the landlord required to give, and in what form?
- How often can rent be raised?
- What happens to the rent when a new tenant moves in?
Questions people ask
Does rent control make renting better than buying?
Not by itself. A cap makes rent increases more predictable while you stay, but the result still depends on the starting rent, the price of the home, the mortgage rate, how long you stay and what you do with the savings.
What rent growth should I use if my province has no cap?
Run a low, middle and high case and see whether the answer changes. Alberta, for example, has no rent-control cap, so a higher case is worth testing rather than assuming a mild increase.
Do rent control rules apply to every rental unit?
Not always. In Ontario, for example, the guideline covers units first occupied before November 15, 2018, while newer units are exempt from it. Confirm coverage for your own unit with your tenancy board.
Are these figures permanent?
No. Guidelines are set each year and rules can be amended. The British Columbia figure in particular should be confirmed each year, so treat the numbers on this page as a 2026 snapshot.
