Joint mortgage application
Everyone on the application is a borrower. The lender reads each income, each credit file, and each monthly debt. The payment they test is the stress-test payment on the one mortgage, not a slice of the payment per person. The co-buying chapter says the lower credit score is the one used for pricing.

Two, three, or four borrowers
Adding a third or fourth borrower can raise the income the lender counts. It also adds that person’s debts and puts them on the covenant. Lenders commonly stop around four. Treat that as a common practice, not a cap written into the guide.
Paid by one person
The payment can leave one bank account. That is a household choice. It does not change the note. Each co-borrower remains liable if the payment is missed, and each co-borrower’s debts still sit in TDS. A co-signer is also liable and, unlike a co-borrower, is not on title.

Transfer to one person
Removing a borrower is not a form you file on your own. The lender re-underwrites the person who will keep the loan, including any money paid to the person who is leaving. A lawyer changes title. Until that closes, both names stay on the mortgage.

Qualification math
Use combined gross income, combined monthly debts, and one insured or conventional mortgage. GDS is 39% and TDS is 44%, matching the affordability calculator. The worked example on this page uses the contract rate, lender, and as-of date from the rates file, and it labels the purchase price as an example.

Registered accounts stay personal
A joint mortgage does not merge FHSA or HBP room. Each eligible first-time buyer uses their own plan. A co-signer who is not a first-time buyer does not collect a second FHSA, and the guide does not treat co-signer status as a CRA rule you can assume.
Frequently asked questions
- What is a joint mortgage in Canada?
- One mortgage with more than one borrower. Lenders commonly allow 2 to 4 people. They qualify combined income and combined debts against one stress-test payment.
- How does a joint mortgage application work?
- Each borrower’s income, debts, and credit are on the file. The payment used for GDS and TDS is the full payment at the qualifying rate, not a per-person share. GDS is 39% and TDS is 44% in the affordability calculator.
- Can a joint mortgage be paid by one person?
- Yes, the payment can come from one account. The other borrowers stay liable, and their debts still count. Paying alone is not the same as being the only borrower.
- Can a joint mortgage be transferred to one person?
- Only if the lender approves the remaining borrower for the loan that is left, including any buyout, and a lawyer transfers title. The co-buying chapter does not describe this as an automatic right.
- Do three or four borrowers each get a payment?
- No. There is one mortgage payment. Extra borrowers change the income and the debts that are tested against that payment.
- Does a joint mortgage give each person a new FHSA?
- No. Each eligible first-time buyer already has their own FHSA and HBP room. A joint application does not add room and does not erase the room of someone who still qualifies.
