Ask “is Polymarket legal in Canada” and the honest answer needs a map, not a yes or no. The international site, polymarket.com, still opens new positions for most of the country’s provinces and territories with no ID check at all. Then, as of July 6, 2026, four provinces — Ontario, Quebec, Alberta and British Columbia — sit in what Polymarket calls close-only mode. Those four happen to be the four biggest by population. Do the math and the site is functionally unavailable for new trades to roughly nine in ten Canadians, even though eight of Canada’s thirteen provinces and territories never touched a restriction list.

The Population Math Behind “Mostly Blocked”

Close-only since July 6, 2026: Ontario (~40% of Canada’s population), Quebec (~23%), British Columbia (~13%), Alberta (~12%). Combined: roughly 88%.

Still open to new positions: Manitoba, Saskatchewan, Nova Scotia, New Brunswick, Newfoundland and Labrador, Prince Edward Island, plus the three territories — together, roughly the remaining 12%.

That gap is why a province-count answer (“six of ten provinces are fine”) and a population-weighted answer (“most Canadians can’t open a new position”) point in opposite directions. Both are true. Neither is the whole picture without the other.

Where the Ontario Piece Actually Came From

Ontario wasn’t part of the July 2026 update — it has been separate, and older, since 2023. The Ontario Securities Commission found that Blockratize Inc., Polymarket’s operator, offered binary options to Ontario residents in breach of the province’s binary-options ban, reaching roughly 28,500 Ontario-based visitors between June 2020 and May 2023. Geo-blocking began in May 2023 once the OSC made contact. The Capital Markets Tribunal approved a formal settlement on April 17, 2025 covering Blockratize Inc. and Adventure One QSS Inc.: a $200,000 administrative penalty, a $22,966.75 USD voluntary payment, $25,000 toward the OSC’s investigation, and two-year market bans for the named operators. Ontario’s geo-block is required to stay in place through at least 2027 as a term of that settlement — this is not Polymarket choosing to be cautious in Ontario. It’s a regulator holding it to a deal.

What changed in July 2026: Alberta, British Columbia and Quebec joined close-only status through a Polymarket terms-of-service update dated July 6, 2026 — no OSC-style settlement, no public tribunal order behind those three. Only Ontario’s restriction traces to an actual regulatory case.

Is Polymarket Legit, or Did the Ontario Case Say Otherwise?

The Ontario settlement is a genuine finding against the company for a specific violation, not a hand-wave. It doesn’t answer a different question — whether resolved markets pay out correctly for users elsewhere — and this page keeps those separate on purpose. A company can be legitimately fined for operating in a jurisdiction it shouldn’t have and still settle its markets honestly everywhere it does operate. Both facts sit next to each other here; neither cancels the other out.

Is Polymarket Safe for a Canadian to Use Right Now?

In an open province: mechanically yes — no KYC gate, real liquidity, the same order book the rest of the world trades against. Safe still doesn’t mean risk-free. A position can resolve to zero like any other trade, and outside a close-only province, there’s no Canadian regulator standing behind an account the way CIRO now stands behind Wealthsimple Predict for Kalshi’s contracts. In a close-only province, the safe move is the boring one: don’t use a VPN to fake a different location. That breaks Polymarket’s own terms and removes what little recourse exists if something goes wrong.

No Canadian Route Onto Polymarket US

Kalshi has Wealthsimple Predict — a CIRO-authorized Canadian app trading a slice of Kalshi’s own contracts. Polymarket has nothing equivalent. Polymarket US, the CFTC-designated exchange run by QCX LLC, requires a US government ID and a US bank account in the holder’s own name; it was built for American residents and has no Canadian onboarding path. So a Canadian shut out of the international site in a close-only province doesn’t have a regulated backup the way a Kalshi-curious Canadian does.
