Ontario is Canada's largest SR&ED market. We help Ontario CCPCs combine federal ITCs with Ontario Innovation Tax Credit (OITC) and Ontario Research and Development Tax Credit (ORDTC) — with T661 and S566 prepared in one workflow.
Federal refundable ITCs plus Ontario provincial credits can stack for qualifying CCPCs
S566 (Ontario) must align with your federal T661 — mismatches are a common audit trigger
Toronto and Waterloo tech corridors mean CRA sees heavy software SR&ED volume — narratives must be specific
Proxy vs traditional method choice affects both federal and Ontario calculations
Federal SR&ED rules apply nationwide. Provincial schedules and credits vary — we prepare both layers where applicable.
