Although I don't necessarily disagree with the last post, I would consider that type of level of caution if new cases are on the rise or at a level greater than what is currently happening. Montreal having a 4,000,000 plus population and an average of 1,000 new cases in the province the math tells me it's not as great of a risk as you might think. But, to your point, it only takes one person coming into contact with to infect you. As the weeks go on I'm thinking the numbers will continue to trend down and your chances for infection will be considerably less.
