Provincial and territorial trade flows by detailed product classification

Provincial and territorial trade flows are estimated using a supply and use framework. These flows represent transactions between suppliers (origin) and final purchasers (destination), rather than the physical movement of goods. For instance, goods purchased by Prince Edward Island from Ontario are recorded as a trade flow between the two provinces, without accounting for transportation through other provinces. Given that trade flows between provinces and territories are estimated using a model, rather than observed transactions, these data are subject to notable revisions as information within the supply and use framework are updated. The magnitude of revisions is likely to be larger at the most detailed product level. 

The point of origin, that is, the original supply source, is where goods are produced or goods are sold out of inventory stocks of producers, wholesalers, and retailers.

The point of destination, that is, the final consumer, is the point where goods are purchased for current consumption, capital formation, input into the production process of other commodities, or added to inventory stocks.

Provincial and territorial trade flows of goods are valued in basic prices, that is prices at which businesses sell their products to others, excluding taxes and transportation costs.

International trade flows of goods use the Free on Board (FOB) valuation, which reflects the price at the point of departure from the exporting country. International trade flows therefore exclude the cost associated with taxes and duties.
