Can Canadians use Polymarket?

It depends on the province. Polymarket's own geoblock lists Ontario, Quebec, British Columbia and Alberta as close-only — existing positions can be closed, new orders are refused. Manitoba, Saskatchewan, the Atlantic provinces and the territories are not listed. No ISP blocked the site on any Canadian network we probed; the gate is Polymarket's, applied by location.

Is Polymarket blocked in Ontario?

Ontario is close-only, not fully blocked: you can close existing positions but cannot open new ones. It is also the only province with a formal enforcement history — the OSC settled with Polymarket's operators on 17 April 2025 under the binary-options prohibition, with a $200,000 penalty plus costs and two-year market bans.

Why did Polymarket block Alberta, British Columbia and Quebec?

Polymarket updated its own terms of use on 6 July 2026, one week before Alberta's regulated iGaming market launched. No public regulatory order exists for any of the three provinces. Alberta's minister Dale Nally put it plainly: Polymarket made the decision itself to geo-fence out of the province.

Do I pay tax on Polymarket winnings in Canada?

There is no settled answer. Winnings can be a tax-free windfall, a capital gain or fully taxable business income, depending on how organized and frequent your trading is. The CRA's windfall factors are in Income Tax Folio S3-F9-C1, and we found no CRA guidance specific to prediction markets. Active, systematic traders rarely keep the windfall treatment — ask a professional.

Is Polymarket available in Canada without a VPN?

The website loads on every Canadian network we probed — no VPN is needed to reach it. Availability is decided at the app level instead: in the four close-only provinces, Polymarket refuses new orders however you connect. OVERDOG routes orders to the same markets through its own gateway, with no VPN in that path either.

Is Polymarket legal in Canada?

Short answer: the restriction is Polymarket's own, not a Canadian block. Polymarket's geoblock list marks four provinces — Ontario, Quebec, British Columbia and Alberta — as close-only: existing positions can be closed, new ones are refused. No ISP blocked the site on any Canadian network we probed, and only Ontario's regulator has taken formal action.

Those four provinces hold 35.8 of Canada's 41.4 million people, about 86% (Statistics Canada, 1 April 2026). So "Polymarket works in Canada" is true for roughly one Canadian in seven. The guides ranking for this question still call Ontario the only restricted province — that stopped being true on 6 July 2026.

This page covers what the Ontario Securities Commission actually ordered, what changed in July 2026, what our own probes measured on Canadian networks, the tax picture, and how OVERDOG routes orders to the same Polymarket markets. Securities and gaming law in Canada is provincial, so your own province's rules can matter too — this page is not legal or tax advice.

Key takeaways

Polymarket is not blocked in Canada as a country. Four provinces — Ontario, Quebec, British Columbia and Alberta — are close-only on Polymarket's own published geoblock list: you can close an existing position but cannot open a new one.
The four close-only provinces hold 35.8 million of 41.4 million Canadians — about 86% (Statistics Canada, 1 April 2026). Polymarket is unrestricted for roughly one Canadian in seven.
Ontario is the only province with a formal enforcement history: the OSC settled with Polymarket's operators on 17 April 2025, with a $200,000 penalty plus costs. Alberta, BC and Quebec were added by Polymarket's own terms change on 6 July 2026 — no public regulatory order behind it.
No Canadian ISP blocks either site: polymarket.com and overdog.bet both answered on every Canadian network we probed — Bell, TELUS, EBOX and TelMAX, 18 August 2026. The restriction is app-level, not network-level.

Is Polymarket banned in Canada?

No — not as a country, and not by any Canadian authority you can point to. There is no federal blocklist naming Polymarket, and polymarket.com answered on every Canadian network we probed. What exists is narrower: Polymarket itself restricts four provinces, in a specific way its documentation calls close-only.

Polymarket's geoblock spec defines the difference precisely. Blocked completely means no new orders and no closing of existing positions. Close-only means you can close what you already hold, but cannot open anything new. Canada's four restricted provinces all sit in the close-only tier, applied on both the website and the API.

That distinction answers the two questions Canadians actually ask. If you hold positions from before July 2026, you can still exit them. If you try to open a new position from Toronto, Montréal, Vancouver or Calgary, Polymarket's own gate refuses the order — no ISP is involved; the venue reads your location.

Geoblock tier	What it means	Where Canada sits
Blocked completely	No new orders and no closing of existing positions	No Canadian jurisdiction is in this tier
Close-only (frontend and API)	Existing positions can be closed; new orders are refused on the site and the API	Ontario, Quebec, British Columbia, Alberta
Close-only (frontend)	Restricted on the website only; the API is not restricted	No Canadian jurisdiction is in this tier

Which Canadian provinces are blocked?

Four: Ontario, Quebec, British Columbia and Alberta. All four appear on Polymarket's published geoblock list as close-only on both the frontend and the API. That is the venue's own machine-readable spec, not a press summary — we read it directly on 19 August 2026, and the table below is dated for that reason.

Together those provinces hold 35,823,609 of Canada's 41,417,056 people — 86% on Statistics Canada's preliminary 1 April 2026 estimates. The honest inverse matters too: Manitoba, Saskatchewan, the Atlantic provinces and the three territories are not on the list at all. Roughly one Canadian in seven lives in a province Polymarket does not restrict.

Province	Code	Status	Since	Basis
Ontario	CA-ON	Close-only, frontend and API	OSC action; settlement 17 April 2025	The only province with a formal enforcement order
Quebec	CA-QC	Close-only, frontend and API	6 July 2026	Polymarket's own terms update — no public regulatory order
British Columbia	CA-BC	Close-only, frontend and API	6 July 2026	Polymarket's own terms update — no public regulatory order
Alberta	CA-AB	Close-only, frontend and API	6 July 2026	Polymarket's own terms update — no public regulatory order

Why Alberta, British Columbia and Quebec were added in July 2026

Polymarket quietly updated its terms of use on 6 July 2026 to restrict the three provinces — one week before Alberta's regulated iGaming market launched on 13 July 2026. There was no announcement, and no provincial regulator has published an order requiring it.

Alberta's own minister confirmed which way the decision ran. Dale Nally, Minister of Service Alberta and Red Tape Reduction, said that “Polymarket made the decision themselves to geo-fence themselves out”. Toronto-based lawyer Evan Thomas added a caveat worth remembering: a formal settlement or regulatory statement may still follow. As of today, none has been published.

Every major guide ranking for this question still describes Ontario as the only restricted province. That was accurate until 6 July 2026. It is not accurate now.

Polymarket in Ontario: the only formal enforcement order

Ontario is the one province where a regulator has actually moved. On 17 April 2025 the Ontario Securities Commission announced a settlement with Blockratize Inc. and Adventure One QSS Inc. — the current and former operators of Polymarket — over conduct between June 2020 and May 2023.

The instrument breached was Multilateral Instrument 91-102, the prohibition on offering binary options to individuals. The settlement carried a $200,000 administrative penalty, a voluntary payment of US$22,966.75, another $25,000 toward the OSC's investigation costs, and two-year market bans, including a ban on trading securities or derivatives.

Two details separate Ontario from the other three provinces. The legal basis is real and public — you can read the OSC's own release, linked below. And yet the switch Polymarket applies is the same: Ontario sits in the same close-only tier as Quebec, BC and Alberta. The difference is the paper trail, not the mechanism.

What the CSA and CIRO actually say

On 2 April 2026 the Canadian Securities Administrators and CIRO issued a joint statement on prediction markets. Two lines in it are routinely misread, and both cut against the loudest claims on this topic.

First, the binary-options prohibition is not national. MI 91-102 applies “in some CSA jurisdictions”, in the regulators' own words. Saying binary options are banned across Canada is a simplification they do not make. Securities regulation here is provincial — another regulator could act tomorrow where the OSC already has.

Second, the same statement notes that two CIRO members have been authorized to facilitate Canadian client access to event contracts, including contracts executed on foreign regulated prediction markets. A compliant route exists in Canadian law — so any page telling you Canadians have no legal path to event contracts is wrong on the regulators' own words.

The statement also carries a warning in the other direction: anyone trading, or facilitating trading, in event contracts that are securities or derivatives must follow registration and other requirements, and failure to comply may lead to enforcement action.

Does Polymarket work in Canada right now?

On the network, yes, everywhere we looked. polymarket.com answered on every Canadian ISP we probed on 18 August 2026 — Bell, TELUS, EBOX and TelMAX. We did not test Rogers, so we will not claim every Canadian network — but we found no sign of any Canadian ISP blocking the site, and no federal blocklist exists.

What decides your experience is the app-level gate. In Ontario, Quebec, BC or Alberta the site loads, you can sign in, and you can close positions you already hold — but a new order is refused once Polymarket's location check resolves you to a restricted province. In the six other provinces and the territories, no Canada-specific restriction applies.

A page that loads is not the same thing as a product you can use. That gap is exactly why the close-only distinction matters — and why guides that only test whether the site loads keep publishing stale answers.

Tax on prediction-market winnings in Canada

There is no single answer, and anyone who gives you one is guessing. The CRA has no fixed label for prediction markets — TurboTax Canada's May 2026 guidance says classification turns on intent, frequency and organization, and we found no CRA guidance specific to prediction markets. Three treatments are possible:

The windfall branch is the one active traders lose. CRA Income Tax Folio S3-F9-C1 lists the factors — no organized effort, no expectation of recurrence, nothing pursued as a profit activity. Prediction markets are widely framed as skill-based, and that framing is precisely what makes the tax-free assumption hard to keep. If you trade often enough to be reading this section, talk to a Canadian tax professional before you rely on any category.

Treatment	Taxable portion	When it applies
Windfall (gambling-style winnings)	Not taxed	Casual, unorganized activity with no systematic strategy
Capital gain	Half of the gain is included in income	Activity that looks like investing
Business income	Fully taxable	Frequent trades, short holds, specialized tools, livelihood intent

Betting on Polymarket markets from Canada with OVERDOG

OVERDOG is an access layer to the Polymarket exchange, not a bookmaker that sets its own lines. Prices come from a real order book set by traders, so there is no bookmaker margin baked in — that is what no-vig means: a description of the price, never a promise about any result. Because there is no house position against you, winning consistently never gets your account limited or closed.

The costs are disclosed together and up front: a flat 1% OVERDOG fee plus Polymarket's own fees. Settlement is on-chain — a winning share redeems for one dollar on Polygon, and you can verify it yourself. There are no bonuses, free bets or deposit matches here, and there never will be. Betting is entertainment, not income; stake only what you can afford to lose.
