They came from this report, from the Government of Canada. It is long and detailed, and well worth your investigation and understanding.
Canada also has idiots running their government and their Covid fiasco.
The USA direction of the effort to handle our Covid is not much better. They have lied to us for 1-1/2 years, ever day, every way and with evil intent.
None of the numbers are real. The reality is the vaccine will never end Covid. But there are methods which can. But they try to subject that.
The wake-up call is near.
