About MapleWage

MapleWage answers one question as precisely as we can: what does a given salary actually pay you, in a given Canadian province or territory?

Why it exists

Canada has fourteen income tax systems running at once — the federal system plus thirteen provincial and territorial ones — layered over CPP or QPP, CPP2, EI, and in Quebec QPIP. Most calculators either cover one province properly and the rest approximately, or flatten the differences until the answer is wrong. We model each jurisdiction on its own terms, including Quebec, which is a genuinely separate system rather than a different rate table.

The standard

• Every figure on this site is computed from published Canada Revenue Agency and Revenu Québec rates. No number is estimated, and no number is written into our copy by hand.
• Our engine is validated against the CRA’s own Payroll Deductions Online Calculator. Where our figure and the CRA’s differ, we investigate before we publish, and we explain any remaining difference on our methodology page.
• When sources disagree with each other, we say so publicly rather than quietly picking one. Our methodology page documents a live example.
• Rates are re-verified on a published schedule, and every page carries the date it was last checked.
