Yes, it's all correct. Interestingly, a case around the peace, order and good government power comes to the Supreme Court about once every 30 years, and we just had one decided a few weeks ago. The carbon tax case was a peace, order and good government case. I litigated it—full disclosure—and the Supreme Court just weeks ago reaffirmed that the federal government can do precisely what you've read out, so yes, whatever needs to be undertaken in an emergency, should Parliament choose to take it up, it can do. Essentially, it is unlimited power, as long as it's time-limited in nature. That was true in the summary you read, and it was true according to the Supreme Court just weeks ago. That this has not been used so far in the pandemic is Canada's cardinal blind spot, marked only by thousands of dead. It's tragic.
