Alberta has won a trade dispute over policies that restricted vegetable oil producers and refiners from selling in Ontario, according to one minister.

Alberta’s intergovernmental affairs minister, Iris Evans, said a panel ruled that Ontario regulations restricting the sale of such products are a barrier to interprovincial trade.

She said for too long Ontario has maintained restrictions that are contrary to its domestic trade obligations.

The Agreement on Internal Trade panel has given Ontario until Feb. 1 to comply or face a penalty of up to $5 million.
