The Ontario Securities Commission has published its Canadian OTC Derivatives 2025 Annual Report, consolidating public data on Canada’s over-the-counter derivatives market and highlighting changes in market size, structure and data quality. The report shows Canada’s OTC derivatives market, measured by gross notional outstanding, increased 12.2% year over year in the fourth quarter to CAD 121 trillion in 2025 from CAD 108 trillion in 2024. New sections cover commodities and Ontario-specific analysis, and the report adds metrics on turnover and risk. It also states that Canada’s share of the global OTC derivatives market, measured by gross notional outstanding, was 9.2% as of June 2025. Rule amendments and compliance reviews materially improved data quality by correcting previously inaccurate results for outstanding positions, average trade size and new transaction counts. The OSC said it will continue efforts to make this data available to investors and other market participants.
