(Wines&Vines) - Oops, she did it again.

British Columbia premier Christy Clark’s bid to restrict supermarket wine sales to wines from her own province has once more triggered a letter of complaint from the countries supplying the majority of wines sold in Canada.

Trade representatives from British Columbia and the United States met July 7 to discuss concerns raised in an April 29 letter signed by the trade representatives of the United States as well as Argentina, Australia, Chile, Mexico, New Zealand and the EU. Together, the countries supply 97.5% of the wine Canada imported last year.

By limiting supermarket sales of wine to B.C. product, B.C. has—in the opinion of Canada’s trading partners—betrayed the country’s international trade commitments under World Trade Organization agreements.

The letter of complaint states, “Accordingly, we request that British Columbia amend the relevant regulations in order to ensure that the sale of wine in grocery stores is permitted on a non-discriminatory basis.” 

This isn’t the first time such a request has been made.
