Canada's agriculture industry has opposed the COOL program since it was enacted in 2009 claiming it forces discriminatory and mandatory labeling requirements on both Canada and Mexico for products sold for retail in the United States. They claim COOL increases processing costs for livestock causing many U.S. slaughterhouses to either refuse taking Canadian-raised cattle and hogs or offer lower prices. Canada's Cattlemen's Association estimates the livestock industry loses in excess of $1.4 billion (including cattle and hogs) each year as a result of labeling requirements.

The Calgary Herald reported Friday that Canadian Cattlemen's Association director John Masswohl is saying the new rules have created more difficulty than ever before by further complicating labeling requirements. According to the report, Masswohl believes the new rules will add to additional costs for Canadian livestock producers who have already absorbed a $25-$40 cost per animal penalty in order to comply with the original program.

It's not just Canadians who are complaining about the new rules.

In a March letter to USDA, Bill Thoni, Cargill's vice president for cattle procurement in the United States said the company's decision to shutdown it's Plainview, Texas, plant in February was due in part to an unreliable cattle supply. The letter expressed concern that the new rules would "create even more difficult segregation requirements that will even further injure production in Canada, Mexico and importantly the United States."
