Health Canada is warning Canadians about counterfeit 3M N95 respirators in light of recent seizures of counterfeit products in Canada and at the border. Health Canada is working with 3M Canada, the manufacturer of authentic 3M N95 respirators, and the Canada Border Services Agency (CBSA) to address the issue of counterfeit 3M N95 respirators, also seen in other countries. 3M has established a hotline and published information on its website to help Canadian customers identify, prevent and report suspected fraud.
