Canada Prediction Market Tax Treatment

Last updated: April 2026 · For Canada residents · Tax body: CRA (Canada Revenue Agency)

The Canada Revenue Agency does not have a dedicated tax framework for prediction market gains. In practice, the CRA classifies them under existing rules for capital gains, business income, or other income — and the classification depends on your trading frequency, intent, and source platform.

Capital gains vs business income

Casual prediction market activity (occasional trades, no professional setup) is generally treated as capital gains, reported on Schedule 3 of your T1 return. Frequent, systematic trading with profit-seeking intent may be classified as business income, taxable at full marginal rates with no 50% inclusion rate. The CRA evaluates frequency, knowledge, time spent, financing, and intention.

T5008 reporting (or its absence)

Canadian-licensed brokers issue T5008 statements summarizing dispositions of securities. Provincial lottery operators do NOT issue T5008 for sports/event contracts. Foreign gray-market platforms (Polymarket, Opinion Trade) issue NO Canadian tax forms at all. The full record-keeping burden falls on you.

Foreign income reporting (T1135)

If you hold foreign property (including USDC on a foreign-controlled wallet) with a total cost basis over CAD 100,000 at any point during the year, you must file Form T1135 (Foreign Income Verification Statement). Polymarket positions held in a self-custody wallet may trigger this depending on how you account for them.

Provincial considerations

Provincial tax follows federal classification — but provincial tax rates vary. Quebec residents file separate provincial returns and may face different treatment of foreign source income. British Columbia, Alberta, and Ontario use federal rules with provincial rate overlays.

Practical record-keeping

For each trade, record: date, platform, market description, position size, cost basis (in CAD using the daily exchange rate), proceeds (in CAD), and net gain/loss. Export trade history from each platform monthly. Convert USDC values to CAD using the Bank of Canada daily exchange rate (the noon rate was discontinued in 2017). Keep records for at least 6 years per CRA retention rules.
