Mr. Speaker, in fact, every step of the way we have responded to science and evolved our advice to Canadians as the science has evolved. As all members in this House know, COVID-19 is a new pathogen and so much about the pathogen is still to be discovered. As we have learned through research, science and the development of evidence across the country, we have revised our advice to Canadians because we know that Canadians understand that science does evolve and that we will provide them information as soon as it becomes available.
In the House of Commons on November 5th, 2020. See this statement in context.
