Canadian money math, done the Canadian way.
Most online calculators quietly use American formulas. Canadian mortgages compound semi-annually. CRA rules have their own thresholds. MapleCalcs tools are built on the exact conventions your bank and the CRA actually use — so the numbers here match the numbers on your statement.

Why another calculator site?
Because the math is usually wrong for Canada. By law, Canadian fixed-rate mortgages compound semi-annually — not monthly like US loans. Most calculator sites ignore this and overstate your payment. Every MapleCalcs tool documents its formula on the page, so you can verify the method yourself.
And because nobody serves Chinese-speaking Canadians. Every tool here ships in English and 繁體中文 — mortgage renewals, CPP timing, and probate fees are confusing enough in your first language.
