The plaintiff brought a class action on behalf of Canadian cattle farmers against the Government of Canada, alleging negligence in its response to the threat of Bovine Spongiform Encephalopathy (BSE), commonly known as 'mad cow disease'.
The plaintiff claimed that Canada failed to implement a ruminant-to-ruminant feed ban in a timely manner and failed to prevent cattle imported from the United Kingdom from entering the animal feed chain, which led to the discovery of a BSE-infected Canadian cow in May 2003 and the subsequent closure of international borders to Canadian cattle and beef.
The court dismissed the action, finding that the claim was barred by section 9 of the Crown Liability and Proceedings Act because the class members had received compensation through various government financial assistance programs.
Furthermore, the court held that Canada did not owe a private law duty of care to the cattle farmers and that its policy decisions regarding the monitoring of imported cattle and the timing of the feed ban were reasonable and did not breach the standard of care.
