Look, I get this question all the time at Openroom. A landlord owns a couple of doors in Ontario, just bought their first place in BC, and asks me, “Same rules, right?” Yeah, no. The two provinces have completely different laws, different forms, and different dispute bodies. Assume otherwise and it’ll cost you. Here are five things I wish every cross-border landlord knew before signing their next lease.

‍

‍1. Nonpayment of Rent: What Happens the Moment Rent Is Late?

In Ontario, the second rent goes unpaid, you can serve an N4 (Notice to End a Tenancy Early for Non-Payment of Rent). That gives your tenant 14 days to pay up or move out. If they pay in full before you actually file with the Landlord and Tenant Board, the notice is dead and the tenancy keeps going.

BC runs on a faster clock. There you serve a 10-Day Notice to End Tenancy for Unpaid Rent. Your tenant has 5 days from getting that notice to either pay everything they owe (which kills the notice) or dispute it with the Residential Tenancy Branch. If they do neither, the tenancy ends on the date you put on the form. Way tighter than Ontario.

2. Roommates vs. Tenants: Is There a Difference?

Yeah, this one trips up a lot of landlords. A tenant, in either province, is someone who actually signed a tenancy agreement with you. That person gets full protection under the Residential Tenancies Act in Ontario, or the Residential Tenancy Act in BC.

A roommate who lives with your tenant but isn’t on the lease isn’t really your problem. Their arrangement is with your tenant, not with you, and the LTB or RTB usually won’t even hear their case. My honest advice: get every adult living in that unit on the lease. If you don’t, you’ll spend the messy moments figuring out who you’re actually dealing with.

3. Deposits: What’s Allowed and What’s Not?

Honestly, this is the one I see landlords get wrong the most. In Ontario, the only legal deposit is Last Month’s Rent (LMR), and it’s capped at one month. Anything else, like a damage deposit, a pet deposit, or a key deposit, is illegal. Yeah, even the pet one. I know.

BC plays a different game. There you can take a security deposit of up to half a month’s rent, plus a separate pet damage deposit of up to another half month. That can add up to a full month combined. You also have to return both within 15 days of the tenant moving out and giving you a forwarding address, with interest. So if you operate in both provinces, please do not assume what’s legal in BC is legal in Ontario. I’ve watched landlords learn that lesson the expensive way.

4. Occupants: Are They Treated Differently?

Occupants are people who live in your unit but aren’t on the lease. Both provinces give them limited rights. In Ontario, only your tenant can file an application with the LTB. Occupants can’t bring their own claim against you, and if you sign a side agreement with them you might accidentally make them a tenant, which is its own headache.

BC works the same way. Only a tenant under a tenancy agreement can apply to the RTB. So if an occupant trashes your unit, you don’t chase the occupant. You serve notice on the tenant, and the tenant is on the hook. Bottom line in both provinces: your contract is with the tenant. Everyone else under that roof is your tenant’s problem to manage.

5. The Dispute Boards: Where Do You Go?

In Ontario, every dispute goes through the Landlord and Tenant Board (LTB). They hear applications from both sides and can order evictions, rent owed, repairs, compensation, all of it. Word of warning though: their backlogs have been brutal for years. You can be waiting months for a hearing.

In BC, you’re going to the Residential Tenancy Branch (RTB) instead. They have two tracks: an informal settlement process and a formal arbitration hearing. Most applications run you $100 to file. Two boards, two different rulebooks. Whichever side of the country you’re on, the same rule applies: skip the process and you’ll pay for it with a slower resolution and a bigger bill.
