I will say that the inspection of masks is not a process of simply doing a look-over. There are machines that are required to inspect N95 masks. The important thing is that once they were in Canada they were inspected by the Public Health Agency of Canada, and they were not distributed to health care workers because they did not meet those specifications. However, 1.8 million masks have been deployed to other areas and are still useable.
