Canadian beef and pork farmers are urging members of Parliament to vote against the United Kingdom’s membership in a major Asia-Pacific trade group.

The farmers, as well as Canadian meat processors, are upset about an announcement Saturday that the U.K. has been granted accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP).

The CPTPP is a trading bloc that includes Canada and ten other nations, comprised of  about 500 million people and 15% of the world’s economy.

But players in Canada’s meat industry say that the U.K. should not be able to join, as Canadian beef and pork producers don’t have fair access to the U.K. market.

One bone of contention is that the U.K. refuses to accept beef treated with growth hormones, which a common practice in Canada.

The meat industry is calling on the federal government to reject the U.K.’s membership in the trading bloc through a vote in Parliament, or compensate farmers and processors for the financial losses that will result.
