Trade data is sourced from four Statistics Canada databases: the Canadian International Merchandise Trade database (CIMT, Table 12-10-0011-01) for international goods; the World Trade in Services tables (WDS, Tables 36-10-0007 and 12-10-0145) for international services; and the Canadian Interprovincial Trade tables (CITH, Tables 12-10-0101-01 and 36-10-0709) for domestic flows.

All values are in current Canadian dollars (nominal, not inflation-adjusted). International goods are customs-based measurements. Interprovincial flows measure trade between provinces — intra-provincial trade is excluded. Services data covers commercial, travel, transportation, and government services at the Canada level (no provincial breakdown for international services).

• Year ranges differ across datasets — goods extend to 2026, services to 2024, domestic services to 2022 • International goods values are summed across provinces and may differ from national aggregates published elsewhere • Interprovincial data uses SUPC product classification (not HS) — no direct concordance between international and domestic product codes • Trailing 12-month snapshot covers international goods exports only
