Can retailers screen customers at the door for entry, e.g. with temperature testing?

Individual screening, such as temperature testing, is technically permissible, yet must be approached very carefully. Be aware that government guidance in this area is sparse yet rapidly evolving. First, avoid any impression of screening customers for any reason beyond a belief that the customer may be exhibiting COVID-19 symptoms. Second, if it is felt that temperature testing is advantageous, take great care to do so in accordance with Canadian privacy principles, e.g. be mindful of consent and of limiting and protecting the personal information that is obtained and shared. Also, staff taking customer temperatures must continue to follow the usual care in observing 2-metre physical distancing limits and other health precautions.
