Can I ask if you're vaccinated?

According to an Angus Reid survey, 75 percent of the people who are unvaccinated don't think it's appropriate to ask people about their vaccination status. More than half of the people with one or more shots say it's perfectly fine to ask. And when it comes to vaccine passports, two thirds of the people who responded, support them for large public events. Those are the issues we take up with Dalhousie University's Wayne MacKay, Constitutional Law Expert and Professor Emeritus of the Schulich School of Law.
