Five jurisdictions tax your payroll directly. Ontario’s Employer Health Tax exempts the first $1,000,000 of Ontario remuneration, on a scale rising to 1.95%, with the exemption withdrawn entirely once the employer or associated group reaches $5,000,000 of Ontario payroll; the annual return is due 15 March. British Columbia exempts the first $1,000,000, charges 5.85% on the slice to $1,500,000 and 1.95% of total remuneration above that, with the return due 31 March. Manitoba’s exemption rose to $2,500,000 for 2026, then 4.3% on the excess to $5,000,000 and 2.15% of total payroll above it. Newfoundland and Labrador exempts $2,000,000 and charges 2%. Quebec’s Health Services Fund runs on a sliding scale to 4.26% above $7,800,000 of payroll – a threshold that stopped being indexed in 2026.
Note how the notch rates work, because they are where the surprises are. Above the upper threshold in British Columbia, Manitoba and Quebec the exemption disappears and the rate applies to total payroll, not to the excess. Crossing that threshold by a dollar can cost tens of thousands. Associated groups share one exemption, and part-year employers prorate it.
Alberta, Saskatchewan, Nova Scotia, New Brunswick, Prince Edward Island and Yukon levy no employer payroll tax at all. Northwest Territories and Nunavut charge 2% of remuneration, but the statutory incidence is on the employee – your obligation is to withhold, remit and file an annual return.
Workers’ compensation is separate, mandatory, entirely employer-funded and set by thirteen different boards. Average 2026 rates run from $0.95 per $100 of assessable payroll in Manitoba and $1.23 at Ontario’s WSIB – its lowest in more than fifty years – to $2.65 in Nova Scotia. Each board also sets a maximum assessable earnings ceiling, and these vary enormously: $79,900 in Nova Scotia against $171,500 in Manitoba. The ceiling caps both your premium base and the injured worker’s benefit, so a low rate on a high ceiling is not always cheaper than the reverse.
