Can two first-time buyers each use their own FHSA?

Yes. Each co-buyer who qualifies as a first-time buyer can contribute to and withdraw from their own FHSA independently. Two first-time buyers can combine up to $80,000 from FHSAs alone, plus up to $120,000 from RRSP HBP.

What is the difference between a co-borrower and a co-signer?

A co-borrower is on both the mortgage and property title — they build equity and share liability. A co-signer is on the mortgage only, helps you qualify, but owns no part of the home and is fully liable if you default.

Do I need a co-ownership agreement when buying with a partner?

Yes — even for romantic partners, especially common-law couples who lack automatic property division rights in some provinces. The agreement covers exit scenarios, cost sharing, buyout terms, and dispute resolution.

How does co-buying affect mortgage qualification?

Lenders combine both incomes but also both debts. They use the lower credit score for rate pricing. Combined GDS is capped at 32% and TDS at 44% of gross household income, calculated at the stress-test qualifying rate.

Quick Answer

How does co-buying a home work in Canada?

Co-buying lets two or more people combine incomes, credit, and savings to qualify for a larger mortgage. Each first-time buyer can access their own FHSA ($40,000), RRSP HBP ($60,000), and Home Buyers' Tax Credit ($1,500). Legal structure matters — choose joint tenancy (equal shares, survivorship) or tenants in common (flexible shares) and always sign a co-ownership agreement before closing.

Combined income increases borrowing power — two $70K incomes qualify for roughly $200K more than one alone
Each first-time buyer gets their own FHSA, HBP, and HBTC — up to $200K registered funds per couple
Co-borrower (on title + mortgage) vs co-signer (mortgage only) — very different risk profiles
Co-ownership agreement ($1,500–$3,000) protects exit, default, and dispute scenarios

Why co-buying is growing in Canada

With average home prices above $650,000 nationally — and detached homes exceeding $1 million in Toronto and Vancouver — roughly 1 in 4 first-time buyers now purchases with someone other than a spouse. Combining two incomes, down payments, and closing costs makes homeownership reachable years sooner.

Legal ownership: joint tenancy vs tenants in common

Joint tenancy means equal shares with automatic survivorship — common for married couples. Tenants in common allows unequal shares (60/40, 70/30) and each owner can leave their share via will — better for friends, siblings, and parent-child arrangements. Discuss structure with a real estate lawyer before closing.

Government programs when co-buying

Each co-buyer who qualifies as a first-time buyer can use their own FHSA ($40,000), HBP ($60,000), and HBTC ($1,500). A couple of first-time buyers could access up to $200,000 from registered accounts. If one buyer is not a first-time buyer, the other still claims their own programs — land transfer rebates are typically prorated by ownership share.

Protect yourself with a co-ownership agreement

Before closing, hire a lawyer to draft a co-ownership agreement covering ownership percentages, cost sharing, exit scenarios (right of first refusal, buyout terms), default remedies, and dispute resolution. Expect $1,500–$3,000 — far less than a $50,000 legal dispute later.
