THE QUICK ANSWER
Overtime may be usable when the lender can verify an acceptable history and continuing income. It is usually assessed as variable earnings rather than assumed to be guaranteed salary. Ask which amount and documentation the proposed lender will accept before building your purchase budget around it.
Separate regular pay from extra earnings
Start with two lines on your own worksheet: guaranteed base pay and overtime actually received. If your earnings also include bonuses, shift premiums or a second job, list those separately. This avoids turning several different types of income into one unexplained annual total.
A regular salary increase and a temporary increase in shifts tell different stories. Your worksheet should make those differences visible. Do not multiply your busiest recent paycheque by the number of pay periods in a year and assume that result is an accepted qualifying income.
Understand the history question
Sagen classifies overtime as variable income. Its published approach normally calls for a two-year history and generally uses the lower of the prior year or the two-year average, with specified exceptions. Those exceptions require a closer review; they do not mean every lender will accept the highest year. Sagen: income and employment underwriting
Canada Guaranty’s buyer workbook also highlights variable earnings as an area where additional income documentation may be needed. Treat an average as a starting calculation to discuss, not a decision you can make on a lender’s behalf. Canada Guaranty: first-time home buyer workbook
Build a clear income summary
Gather the records requested for your application and put them in date order. In a separate note, explain why overtime rose or fell: a temporary project, a change in shifts, time away from work or a different role. Keep that explanation factual and distinguish what has happened from what you hope will happen.
Ask whether your employer can clarify the nature of the additional work. You are seeking an accurate description, not a promise of hours the employer cannot guarantee. If different documents show different totals, identify the reason rather than silently choosing the larger number.
A hypothetical overtime calculation
Suppose a buyer has a $70,000 base salary and earned $8,000 and $12,000 of overtime in the last two completed years. The simple average of those overtime amounts is $10,000. Adding that average to the stated base produces an $80,000 planning figure, but only if the lender accepts both components on that basis.
If the overtime history were reversed, or this year’s extra shifts had stopped, the question would change. The example shows the arithmetic, not an approved income. Ask for the actual qualifying amount before using it in an affordability calculation.
What lenders may consider
Be ready to explain the source of the pay, the history behind it, what current records show and whether the job itself has changed. Other parts of the mortgage file still need attention, including debts, credit, down payment and the property. Extra earnings do not replace that review.
For your own comfort, try a household budget that does not rely on every extra shift. Ask whether you could still manage the proposed payment if overtime slowed for several months. That personal planning exercise is different from a lender’s qualification calculation, and both deserve attention.
Common mistakes to avoid
Do not count the same overtime twice by adding it to a salary figure that already includes it. Avoid treating an advertised earning potential as income received. Check whether the figure on a document refers to a full year, year-to-date earnings or one pay period before comparing it with another figure.
Another mistake is requesting documents only after finding a property with a short financing deadline. Start the income review early, particularly if old payroll records take time to obtain. Keep sensitive pay and tax documents out of general email enquiries and website chat; ask for the appropriate secure process.
A FEW MORE QUESTIONS
Frequently asked questions
Can one unusually strong month of overtime establish my annual income?
It should not be assumed to. Show the wider pattern and ask which income figure the lender will use; a single busy period can give an incomplete picture.
What if I changed employers but still work overtime?
Provide the dates and pay information from both roles. Ask how the change affects the treatment of the overtime history instead of assuming it transfers automatically.
Can I qualify using base pay alone?
You can ask Vijay to explore that scenario. It may give you a useful comparison, but the available mortgage depends on the full application and lender assessment.
