There are only two laboratories at level 4, and they belong to the federal government and are situated in Winnipeg. There are approximately 130 level 3 laboratories. We believe the majority of those—almost all—are already importing pathogens. They essentially already have permits under the human pathogen importation regulations, so we know they're following laboratory safety procedures.
Again, with that in mind, we do not believe the regulatory and programmatic elements will have massive impacts on these laboratories, which are already following laboratory biosafety guidelines.
For select level 3 and 4 laboratories, we are going to be looking at security clearance applications. So that would certainly be one of the key elements that will impact them.
