How Many Occasional Days Before a Lender Counts Your Income

There is no fixed number of days. A lender takes a two-year average of your occasional earnings from your T4s and Notices of Assessment, so the number of days you work matters only through the total income those days produce.

Key takeaways

• A lender averages two years of occasional earnings from your T4s and NOAs, not a day count.
• Occasional daily pay across published boards ran from 286 to 294 dollars for 2025-26.
• Days times a daily rate gives annual income; the two-year average is what the lender uses.
• Income runs through a qualifying rate and the 39% GDS and 44% TDS ceilings to reach a mortgage amount.
• A long-term occasional contract changes the picture because pay is the grid rate prorated by 1/194 per day.

The lender averages what you actually earned

A lender does not set a day threshold for occasional work. It takes a two-year average of what you earned and uses that figure. So the question is not how many days, it is how much those days added up to.

Occasional pay is a daily rate. Across the published board grids for the 2025-26 school year, the daily occasional rate ran from 286 to 294 dollars. The number of days you accept turns that daily rate into an annual total. More days worked means a higher total. Fewer days means a lower one. The lender reads the total, then averages the last two years to smooth out a strong year against a lighter one.

• 286 to 294 Daily occasional rate, 2025-26 (Lowest and highest across published board grids)
• 2 years Income the lender averages (From your T4s and Notices of Assessment)

Why the average: Occasional income moves month to month. A two-year average gives the lender a stable number it can rely on, instead of guessing from a single busy or quiet stretch.

Days into dollars into a mortgage

The chain is short. Daily rate times days worked gives your annual income. Two years of that income, averaged, is the figure the lender uses. That figure runs through a qualifying rate and the debt ratios to land on a maximum mortgage.

The qualifying rate is the contract rate plus 2 percentage points, or the 5.25% floor, whichever is higher. In the examples below the contract rate is 4%, so the qualifying rate is 6%. The lender then holds housing costs to 39% of gross income (GDS) and total debt payments to 44% (TDS), over a 25-year amortization, with 250 dollars a month for property tax and 100 dollars for heat built in.

Read the first two rows as the start of the grid at the lowest and highest published boards, and the last two as the top of category A4. An occasional teacher who works enough days to reach a given total is read the same way as a contract teacher sitting at that salary. The source of the income is occasional days; the number the lender uses is the total. These are model figures. A lender uses the exact salary on your documents and your actual debts.

The paper that proves it

Occasional income is proven on paper, not by a day count you quote. The lender wants to see the earnings land in your T4s and your Notices of Assessment, then match them to pay records from the board.

The list letter matters. T4s and NOAs show the past. The letter shows you are still on the roster and the work can continue. See Documents teachers need for a mortgage for the full set.

• Two years of T4 slips, showing your occasional earnings from the board.
• Two years of Notices of Assessment from the CRA, which confirm the income you filed.
• Pay history from the board, which shows the days and amounts behind the T4 totals.
• A letter confirming you are on the occasional list, so the lender knows the work is ongoing.

What moves the needle this year

Because the lender reads a total, the thing that moves your number is a higher total with a clean record behind it. Three moves help, and a long-term occasional contract changes the picture entirely.

Run your own totals through the Teacher affordability calculator to see where your average lands, and read Occasional and supply teacher mortgages for how a lender frames the file.

• Accept more days when you can. Each day at the 286 to 294 daily rate adds to the annual total the lender averages.
• Keep your own records. Pay stubs and a running count of days make it easy to tie the board's pay history to your T4s.
• Avoid long gaps that the lender cannot explain. A steady pattern reads as reliable income; a sudden drop invites questions.

When an LTO changes things: A long-term occasional contract is paid as the grid rate prorated by school days, which boards commonly express as 1/194 of the annual rate per day, against the standard 194-day school year. That is a contract salary a lender can read directly, rather than a two-year average of scattered days.
