As far as I know, the most advanced Canadian vaccine is Medicago's. It's too bad the company representatives aren't here anymore. As you know, Medicago hasn't completed its phase three trials, so the vaccine still can't be produced in Canada. The company received support to develop a vaccine in Canada, but it will be years before doses are produced in Canada.
Yes, starting work on vaccine production is crucial, but a vaccine isn't going to be ready in a few months. It takes a long time to build the ecosystem necessary for domestic production. I'm not saying we should wait, far from it, but I think this is where we would have been anyways.
