Nova Scotia is putting in place a policy to require people to show they are fully vaccinated before being allowed to do non-essential activities. Those include going to restaurants, gyms and live performances as we head into Phase 5 of the reopening plan. Government says it's only temporary, until the threat of a fourth wave driven by the Delta Variant passes. Is there still an argument that it is a violation of their Charter Rights? For his opinion, I spoke with Professor Emeritus of the Schulich School of Law, Dalhousie's Wayne MacKay.
