Up until early April you stated that asymptomatic persons shouldn't wear a mask as it didn't work or was harmful, and then on April 6 you changed your mind and said a mask was good for additional protection. You insisted to Canadians, time and again, that COVID-19 didn't transfer from human to human, but Dr. Maria Van Kerkhove of the WHO admitted in April 13 that, and I'm quoting, “Right from the start, from the first notification we received on the 31st of December, given that this was a cluster of pneumonia...immediately thought, given that this is a respiratory pathogen, that of course there [may] be human-to-human transmission.”
Canadians are confused. Why had we been told that science has the answers? Canadians are looking to you as a top science official in the country. They don't understand why your message changed so much. Why did you lead Canadians so far from the known scientific fact that masks do work?
