Real numbers from this tool, line by line.
$7,392 of wage subsidy is what an Ontario small business with two summer students loses if its Canada Summer Jobs application misses the federal funding application deadline.
That number comes straight out of the calculator with these inputs: 2 jobs, 35 hours a week, 12 weeks, $18.50 an hour paid, Ontario adult minimum wage $17.60, private sector. CSJ reimburses $8.80 an hour, which is $3,696 per job and $7,392 in total. You can ask for an advance of up to $5,544 and the last $1,848 arrives after your Payment Claim.
The date
ESDC's Applicant Guide says the CSJ 2027 call for applications opens October 27, 2026 at 9:00 am Eastern. The closing date is published when the call opens. Last year's call closed December 11, 2025 at 11:59 pm Pacific, and the guide is blunt about late files: applications received or postmarked after the deadline are not considered. The subsidy simply is not there for that summer.
Why the subsidy is smaller than you think
The most common mistake is multiplying the wage you pay. CSJ does not do that. A private or public sector employer gets up to 50% of the provincial adult minimum wage, not 50% of your wage. Pay $18.50 in Ontario and CSJ still works from $17.60, so the rate is $8.80 an hour.
Three more rules shape the number:
- Funded hours stop at 40 a week and funded weeks at 16. A job planned at 45 hours for 18 weeks is funded as 40 hours for 16 weeks.
- A job under 30 hours a week does not meet the full-time rule. At 25 hours the calculator shows $0, because ESDC may refuse those wages unless it consents in advance.
- Mandatory Employment Related Costs (CPP or QPP, EI, vacation pay, workers' compensation) are reimbursed only to not-for-profits.
The same two jobs at a not-for-profit
Switch the sector to not-for-profit and the rate becomes 100% of the minimum wage, $17.60 an hour. With a 12% MERC rate typed in, the same two jobs bring $16,558.08, and the advance can reach $12,418.56. That is why not-for-profit directors and small business owners should not share one rule of thumb.
Cash timing
The advance limit is 75% of the agreement for projects of $100,000 and under and 50% above that. The balance is paid when you file the Payment Claim and Activity Report, due within 30 calendar days after the last CSJ job ends (Articles of Agreement, section 6.1). If your two jobs end on August 22, 2027, the claim is due September 21, 2027.
What to do before October 27
- Check your CRA payroll deductions (RP) business number. CSJ requires it.
- Set up and verify your GCOS account. ESDC recommends doing it before the deadline.
- Count your full-time employees across Canada. Private employers must have 50 or fewer.
- Run your own numbers in the free calculator and copy the subsidy into your job details.
Free and paid
The web calculator is free and gives all 12 result lines for one job profile, as often as you want. The full version is an .xlsx that adds a Job Lines & Claim Dates sheet: up to 10 different positions with their own start dates, weeks, hours and wages, the total advance and the Payment Claim due date, saved for your bookkeeper. ESDC may approve fewer jobs, weeks or hours than you request, so treat the result as the maximum.

Questions people ask
What does this Canada Summer Jobs calculator work out?
It takes your jobs, hours, weeks, wage and sector and returns the CSJ wage subsidy at stake: 2 private-sector jobs at 35 hours for 12 weeks in Ontario ($17.60 minimum wage, $18.50 paid) give $8.80 an hour, $3,696 per job and $7,392 in total, with an advance of up to $5,544 and $1,848 paid on the final claim.
Who is this for?
Owners and office managers of Canadian private businesses with 50 or fewer full-time employees, public-sector employers and not-for-profit directors who apply to Canada Summer Jobs and must file before the federal funding application deadline. It fits any province: type your own adult minimum wage.
Why not use a general payroll calculator?
A general calculator multiplies the wage you pay. CSJ reimburses private and public employers only 50% of the provincial adult minimum wage, funds at most 40 hours a week and 16 weeks, and pays MERCs only to not-for-profits. Get that wrong and your application budget does not match the agreement.
What is free and what is in the full version?
The web page gives the full check for one job profile on screen, with all 12 result lines, as often as you like. The $21 .xlsx adds up to 10 different job lines with start dates, end dates, the advance and the Payment Claim due date 30 calendar days after the last job ends, saved per summer.
What does missing the deadline cost?
ESDC states it will not consider applications received or postmarked after the deadline. For 2 Ontario private-sector jobs at 35 hours for 12 weeks that is $7,392 of wage subsidy, and you still pay every wage and MERC yourself. The 2027 call opens October 27, 2026 at 9:00 am EST.
When do the Canada Summer Jobs dates change next?
The CSJ 2027 call for applications opens October 27, 2026 at 9:00 am EST (canada.ca Applicant Guide, updated September 29, 2026). ESDC will publish the 2027 closing date and job dates when the call opens; the 2026 call closed December 11, 2025 at 11:59 pm PST. Provincial minimum wages also change during the year.
