Prior to 1995, Canada had a range of measures which placed limits on dairy product imports in order to maintain the stability of its national milk supply management system. These controls changed significantly in 1995, however, as a result of the World Trade Organization (WTO) Agreement on Agriculture whereby Canada and other signatories agreed to replace quantitative import restrictions with tariffs and tariff rate quotas. This effectively moved Canada into a much more global marketplace. Under this agreement, most dairy products are subjet to tariff rate quotas (TRQs). Summaries of tariff rate imports and lists of quota holders can be viewed on the Global Affairs Canada website.
In 2014, imports of dairy products totaled 201,667 tonnes and exports reached 95,258 tonnes. Imports of dairy products have been consistently higher than exports due to a continuous increase in the strength of the Canadian dollar and market structure. Demand for products such as dairy protein ingredients is rising steadily and cannot be entirely supplied by domestic production.
Volumes imported under the Import for Re‐Export Program (IREP) have been significant. Dairy products imported under the IREP are mainly used to manufacture further processed food products for the export market. Imports under the IREP increased 1% to 54,347 tons. In 2014, the IREP imports accounted for 36% of total dairy imports (in volume). Canada is not a large exporter of dairy products. Our milk and dairy production is primarily to meet domestic requirements. Major Canadian dairy exports include ice cream and cheese.
