$280,000 in Seattle ≈ CA$314,169 in Toronto

For a family of four, this comparison produces a different answer than a single-person look at the same cities. Childcare costs, parental leave policy, and the second earner's tax treatment all push the number. With a partner at 60% of the primary salary and two kids in daycare, a $280,000 household in Seattle needs CA$314,169 in Toronto to keep the same net cash.

Childcare is the biggest single swing factor in this comparison. Seattle households pay $30,000 per year; Toronto caps it at CA$5,760 via subsidy. That difference flows directly to net cash. A standard salary comparison won't show it at all.

Parental leave: Toronto provides 28 weeks paid vs 7 in Seattle. A new child in the first year of the move is exactly the scenario where that gap shows up as real money (and real stress avoided).

With kids in the house, healthcare is the line that quietly compounds. Toronto runs a universal system, so a rough year doesn't turn into a billing event. The Seattle side carries $10,640 a year in premiums and out-of-pocket costs, exposure that simply doesn't follow you across.

K-12 schools score higher on PISA 2022 in Canada (506 (math 497, reading 507, science 515)) than in USA (489 (math 465, reading 504, science 499)), a 17-point gap on the OECD's standardized 15-year-old assessment. PISA is one signal; local school choice and curriculum philosophy matter at least as much.

The second-earner question is worth running separately. In high-childcare-cost cities, full-time daycare can eat most of a partner's after-tax income. In Toronto, subsidized childcare changes that math entirely: both salaries actually make it to the household. Use the "Partner works in" toggle in the calculator to see what that shift does to your specific numbers.
