Two governments, two tax bills
Canadians pay income tax twice over: once to Ottawa and once to their province, on the same income, using two entirely separate sets of brackets. The federal side runs 14% / 20.5% / 26% / 29% / 33% for 2026 — the lowest rate came down from 15% this year. The provincial side is set independently by each province, and the differences are large enough that the province you live in matters more than most people assume. On top of both sit CPP (or QPP in Quebec) and EI contributions.
On a $70,000 salary in Ontario that works out to $8,243 federal tax, $4,140 Ontario tax, $3,957 CPP and $1,123 EI, leaving $52,538. Change only the province and the answer moves — see the income tax calculator.
What the province actually costs you
The same $100,000 salary, the same federal tax, four different outcomes:
| Province | Federal tax | Provincial tax | Take-home |
|---|---|---|---|
| British Columbia | $14,393 | $5,902 | $73,935 |
| Alberta | $14,393 | $6,954 | $72,883 |
| Ontario | $14,393 | $7,128 | $72,710 |
| Quebec | $12,018 | $13,629 | $68,068 |
A gap of $5,867 a year between British Columbia and Quebec on an identical salary — before considering that Alberta charges no provincial sales tax while the others do. Moving province is one of the few decisions that changes a Canadian's tax bill materially without changing their job.
Quebec's 16.5% federal discount — and why it still costs more
Look at the federal column above: Quebec residents pay $12,018 where everyone else pays $14,393 on the same income. That is the Quebec abatement, a 16.5% reduction in federal tax that exists nowhere else in Canada. It is worth $1,360 at $70,000, $2,375 at $100,000 and $4,365 at $150,000.
It is not a gift. Quebec runs programs that Ottawa administers in the rest of the country — its own pension plan (QPP), its own parental insurance (QPIP) and its own income tax collection — and the abatement compensates for that. The province then charges its own, higher, provincial rates to fund them. The net result is visible in the table: Quebec residents receive the only federal discount in the country and still take home the least. Any comparison that quotes the abatement without the provincial rates gives you exactly the wrong impression.
Ontario's surtax: a tax charged on your tax
Ontario's posted rates top out at 13.16%, but that is not what high earners pay. Ontario levies a surtax calculated on the provincial tax you owe — not on your income. It adds 20% of provincial tax above one threshold and a further 36% above a second, and it appears nowhere in the rate table:
| Salary | Ontario tax before surtax | Surtax | Increase |
|---|---|---|---|
| $90,000 | $5,370 | $0 | — |
| $120,000 | $8,360 | $837 | +10.0% |
| $200,000 | $17,788 | $6,117 | +34.4% |
At $200,000 an Ontario resident's provincial bill is over a third higher than the published rates imply. Ontario also charges a separate Health Premium that steps up with income. Both are included in our Ontario figures; neither is visible if you simply apply the bracket percentages yourself.
Two ceilings where your marginal rate falls
CPP contributions stop at a first earnings ceiling, then a second tier applies at a lower rate up to a higher ceiling, after which they stop entirely. EI has its own ceiling. The effect on an Ontario salary is two visible steps down:
| Salary | Marginal burden |
|---|---|
| $70,000 | 35.60% |
| $75,000 | 33.65% |
| $86,000 | 29.65% |
Someone earning $86,000 keeps more of their next dollar than someone earning $70,000 — the contribution ceilings, not the tax brackets, are doing that.
What the calculator covers — and what it doesn't
- Four provinces: Ontario, British Columbia, Alberta and Quebec. The territories and the remaining provinces set their own rates.
- Basic personal amounts only. The spousal amount, disability credit, tuition credits and the Canada employment amount are not applied.
- RRSP contributions are not deducted, and they are the single most effective way for most Canadians to reduce taxable income.
- Benefits are excluded — the Canada Child Benefit, GST/HST credit and provincial credits can be worth thousands at lower incomes.
- Sales taxes are not modelled. GST/HST/PST differ sharply by province and change the real cost of living behind these numbers.
Federal figures come from the CRA for 2026; provincial rates from each province's published schedule. If something looks wrong, please tell us — our methodology explains how every calculator is checked before it goes live.
