You've probably seen the headlines or heard the chatter at the coffee shop. Rent is the single biggest expense for most of us in Ontario, and every year, we wait for that one number to drop from the provincial government. For 2025, that number is out. It’s 2.5%.
But here’s the thing. That 2.5% figure isn't the whole story. Honestly, if you just look at that number and assume you're safe (or that you're limited as a landlord), you might be in for a massive surprise.
The Ontario rent increase 2025 rules are a weird mix of strict caps, total exemptions, and legal loopholes that can make your head spin. Let's break down what's actually happening on the ground.
The 2.5% Cap: Who Does It Actually Protect?
The 2.5% guideline is basically the province's way of saying "slow down" to landlords. It applies to the vast majority of renters. If you live in a "standard" apartment, a rented house, or a basement suite that was occupied before a very specific date, your landlord can't just hike your rent because their mortgage went up.
They are capped at that 2.5% for any increase taking effect between January 1 and December 31, 2025.
Wait.
There is a massive catch.
This protection only exists if your place was first occupied for residential purposes before November 15, 2018. If your condo was built in 2019? You aren't protected by the cap. If that basement apartment was finished and rented out for the first time in 2021? No cap.
For those newer units, the "wild west" rules apply. A landlord can technically ask for a 10% increase or even a 20% increase. It happens. It sucks, but it's the law as it stands right now.
The "Post-2018" Trap
I talk to people all the time who moved into a shiny new glass tower in downtown Toronto or a brand-new townhouse in Kanata, thinking they were covered by the Ontario rent increase 2025 guidelines. They weren't.
If your building is "new" (post-November 2018), your landlord still has to follow some rules:
- They must give you 90 days' notice.
- They can only raise the rent once every 12 months.
- They usually have to use an N2 form instead of the standard N1.
But the actual dollar amount? That’s up to them. If they want to raise your rent from $2,200 to $2,800, and you’re in a new build, your only real move is to negotiate or move out.
How Landlords Go Above the 2.5% (The AGI)
Even if you live in an older, rent-controlled building, that 2.5% isn't always a hard ceiling. Landlords can apply for something called an Above Guideline Increase (AGI).
Essentially, they go to the Landlord and Tenant Board (LTB) and say, "Hey, I spent $200,000 replacing the roof and the boilers, and I need the tenants to help pay for it." Or maybe the municipal property taxes jumped by an "extraordinary" amount.
If the LTB agrees, they can allow an extra 3% on top of the 2.5% guideline.
This usually happens in big apartment blocks managed by corporations. If you get a notice saying your rent is going up by 5.5%, check the fine print. It usually says "subject to LTB approval." You don't actually have to pay the "extra" bit until the board approves it, but if they do approve it six months later, you might owe a big chunk of back-pay. Kinda stressful, right?
The N1 Form: Your Paper Shield
Never, ever accept a rent increase via text message.
"Hey, rent is going up $50 next month. Thanks!"
Nope. Not legal.
To make the Ontario rent increase 2025 official, a landlord must serve a formal N1 Notice. This piece of paper is your protection. It has to be dated correctly. It has to give you a full 90 days of lead time. If your landlord gives you the notice on January 1st, the increase can't start until May 1st.
If the math is wrong, or if they haven't waited a full 12 months since your last increase, that paper is basically garbage. You can keep paying your old rent, though it's usually better to politely point out the error first to keep the relationship from souring.
What Most People Get Wrong About Market Rent
There’s a common myth that if the "market rent" for your neighborhood goes up, your landlord can raise yours to match it.
That is 100% false for rent-controlled units.
If you’ve lived in your apartment for ten years and you’re paying $1,200 while the guy next door just moved in at $2,500, your landlord is still stuck with that 2.5% cap for you. They cannot force you to pay "market rates" just because the city got expensive. This is why "long-term" tenants are often the ones landlords try to nudge out—they want to reset the unit to the current market price, which they can only do once the unit is vacant.

Practical Steps for Tenants and Landlords
If you're a tenant:
- Verify your "birthday." Check exactly when your building was first lived in. If it’s pre-November 15, 2018, breathe a sigh of relief. You’re capped at 2.5% for 2025.
- Watch the calendar. If you get a notice today for an increase in two months, it’s void. You are entitled to 90 days.
- Keep the N1. If you ever have to go to the LTB, that form is your Exhibit A.
If you're a landlord:
- Don't get cute with the dates. The LTB is backed up, but they are sticklers for the 90-day rule. One day short and your whole application could be tossed.
- Calculate the 2.5% exactly. Don't round up to the nearest ten dollars. If the math is $1,537.50, don't write $1,540.
- Think about the relationship. In 2025, the market is shifting. Sometimes keeping a great tenant who pays on time is worth more than an extra $40 a month.
The Ontario rent increase 2025 guideline of 2.5% is lower than inflation was in previous years, which is why some landlords are feeling the pinch. But for tenants, even 2.5% on a $2,500 rent check is an extra $750 a year.
It’s a balancing act that rarely makes everyone happy. Just make sure you know which side of the 2018 line you’re standing on before you sign anything.
Actionable Next Steps:
- Check your building's history: Look up your address on a site like UrbanToronto or check the initial occupancy permits via the city's building department to confirm if you are truly rent-controlled.
- Download the official N1 Form: Both parties should visit the Tribunals Ontario website to ensure the most recent version of the form is being used, as outdated forms can sometimes lead to technical dismissals.
- Review your lease for "Discounts": Some landlords provide a "rent discount" in the first year. Check if your 2.5% increase is being calculated based on the discounted rent or the lawful rent stated in the contract, as this is a frequent point of legal dispute.
