What a trade to Toronto does to an athlete’s taxes

A player traded to Toronto changes tax systems mid-season — and the decisions made in the first weeks can echo for the length of a contract. This File explains why the tax question is the highest-stakes invisible item on any Toronto arrival’s list.

Does an athlete traded to Toronto pay Canadian tax?

Broadly: Canada taxes residents on worldwide income, and it taxes non-residents on income earned in Canada. Where a traded player lands on that spectrum depends on residency — a facts-and-circumstances test that looks at where their home, family and economic life actually sit. Per the CRA’s residency folio, a person who sojourns in Canada for 183 days or more in a year is deemed resident for that whole year, and the Canada–US treaty’s tie-breaker rules settle it when both countries claim the same person.¹ Days are not an abstraction: John Tavares’s own appeal argues he spent 45 days in Canada in the last months of 2018 and was a US resident when his signing bonus was paid, as Global News reported.²

Why do athletes’ taxes make headlines in Toronto?

Because the structures are distinctive and the amounts are large. Signing bonuses are treated differently from salary under the treaty: Article XVI caps tax on an inducement to sign at 15% of the payment when it crosses the border³ — and whether Tavares’s 2018 bonus was an inducement or salary is the exact question in the CRA’s $8-million reassessment, which CBC Sports set out when he took the agency to court in 2024.⁴ The case went to trial at the Tax Court of Canada in Toronto in August 2026. Tavares testified;⁵ so did former Leaf Patrick Marleau, who told the court the 15% treatment was a lever the club used to entice players to Toronto.⁶ As of this File’s update date, no decision has been reported. Marleau and Jake Muzzin have separate appeals of their own,⁷ the NHL and NHLPA are watching the outcome — the league’s deputy commissioner says it has its own issues with the CRA’s interpretation⁸ — and tax columnists have argued the CRA’s position would discourage American players from signing north of the border.⁹ Retirement Compensation Arrangements exist in large part because of cross-border athletes, and in December 2024 the Tax Court ruled for former Blue Jays Russell Martin and Josh Donaldson in their RCA dispute with the CRA;^10,11 Jose Bautista’s separate RCA dispute has also been reported.¹² None of this is exotic to specialists; all of it is exotic to a player who had five days’ notice.

What is the “duty day” system?

Athletes are taxed by the jurisdictions where they work — and they work wherever the schedule sends them. Income is commonly allocated by what practitioners call duty days: days spent practising, travelling and playing in each jurisdiction. The Hockey News published a team-by-team study, prepared by a KPMG cross-border specialist, of what a player on the same salary actually keeps depending on the club — with the home-and-road allocation built in.¹³ A Toronto player still pays US states for US road games; a US-based player pays Canada for Toronto games. The trade changes the denominator overnight.

What actually needs to happen in week one?

One thing: a cross-border tax specialist engaged before the first Canadian paycheque — because elections, structures and residency positions are much easier to set up correctly than to repair. The player’s job is a single phone call; the specialist does the rest.

The short version

Residency drives everything. Signing bonuses and salary behave differently. Duty days decide who taxes what. And the first paycheque is the deadline that matters.

This File is general information about how cross-border athlete taxation is publicly understood to work, verified against the sources listed below at the date above. No decision in the Tavares case has been reported as of this update — this File will be revised when the Tax Court rules. It is not tax advice; players use licensed cross-border tax professionals for their situations.
