Most people assume mortgage qualifying is about how much you earn. It's really about how much of what you earn a lender is willing to count, and how confident they are it will still be there in year three.
That's why two people with the same bank balance can get very different answers. One has a salary and a two-year history. The other just changed careers, picks up overtime, and runs a side business. Same money, different paperwork, different result.
Here's how the main income types are treated, in plain English, so you know where you stand before anyone pulls a credit report.
The two things every lender wants to see
Stability and provability. Stability means the income has a track record and a reasonable future. Provability means it shows up on documents a lender can verify: pay stubs, a job letter, T4s, a Notice of Assessment, bank statements.
If your income is both, qualifying is mostly arithmetic. If it's only one of the two, there's usually still a path, it just takes a little more planning. If it's neither yet, the honest answer is that it's a timing question, not a no.
Salaried and hourly
A full-time salary with a job letter and recent pay stub is the simplest case. Lenders use your base salary as-is.
Hourly works the same way if your hours are guaranteed. If they vary, most lenders average your earnings over the last two years using your T4s, or use the guaranteed minimum if that's all they can confirm.
Still on probation? Many lenders want probation finished before they rely on the income. Some will proceed with a strong job letter, especially if you're staying in the same field. It's worth asking before you assume you have to wait.
Overtime, bonuses and commission
Variable pay is counted, but usually as a two-year average rather than your best year. If this year's overtime is a big jump from last year's, expect the lender to lean on the lower number.
Commission-only income follows the same rule: two years of T4s or Notices of Assessment, averaged. A new commission role with less than two years of history is one of the most common reasons a strong earner qualifies for less than expected, so plan the timing if you can.
Contract, seasonal and part-time
Contract income is usable when there's a history of renewals or a clear pattern of continuous work in your field. A single first contract is harder to count on its own.
Seasonal work and part-time hours are typically averaged over two years as well. A second part-time job can be included if you've held it long enough to show it isn't temporary.
Self-employed
If you own a business or invoice for your work, lenders generally average the income you declared on your last two Notices of Assessment. The income you report is the income that counts, which is where write-offs that save you tax can cost you borrowing room.
Some lenders look at business bank deposits or add back certain expenses to reflect what you actually earn. Those programs exist, they just come with their own paperwork and pricing. If you're self-employed and thinking about a home, the earlier we talk, the more room there is to plan your filings around it.
Parental leave and other leaves
On maternity or parental leave, many lenders will use your full return-to-work salary when your employer confirms your position and return date in writing. The benefit you're receiving in the meantime isn't usually the number they use; the job you're going back to is.
Medical or disability income can be counted when it's ongoing and documented. Short-term benefits with an end date generally aren't.
Pension and retirement income
Canada Pension Plan, Old Age Security, workplace pensions and annuities all count when they're regular and documented, usually with a benefit statement or T4A. Investment and RRIF withdrawals can sometimes be used too, depending on how long they've been paid and how much is left behind them.
Rental, support and other income
Rental income counts in part, often a percentage of the rent, backed by a lease and sometimes your tax return. Child or spousal support counts when it's court-ordered or in a signed agreement and has a history of being paid. Gifts and one-time windfalls help with the down payment, not with qualifying income.
Between jobs right now
This is the one people are most nervous to say out loud, so let's say it plainly: Employment Insurance and other temporary benefits generally aren't counted as qualifying income, because they're designed to end.
That doesn't mean the plan stops. It means the order changes. Three things move the needle:
A signed offer for your next role. Many lenders will work with a firm start date and a job letter, sometimes before your first pay stub arrives, particularly if you're staying in the same field.
A co-applicant. A partner, parent or sibling with stable income can be added to the application. Their income is added to yours for qualifying, and they share responsibility for the mortgage. Our co-applicant guide covers how to choose well.
Timing. If a new job is six months out, the smartest move might be getting the down payment plan and credit in order now, so that the day the income is provable you're ready to go.
What a lender actually does with the number
Once your usable income is set, lenders compare it to your housing costs and your total debts. Housing costs, including the stress-tested mortgage payment, property taxes, heat and half of any condo fees, generally need to sit under about a third of your gross income. Add your other debt payments and the total generally needs to stay under the low forties as a percentage.
That's why reducing a car payment or a credit card balance can raise what you qualify for just as effectively as earning more. Our affordability calculator shows how those ratios play out for your numbers.
The short version
Lenders count income that's steady and provable, average income that moves around, and lean on what you're going back to rather than what's tiding you over. If your income is in transition, you don't need to guess whether you qualify. Tell us where things stand and we'll map the timing with you, no credit check required to have that conversation.
