This week, Transport Canada enforced mandatory temperature checks at four of Canada's busiest airports, in Toronto, Vancouver, Calgary, and Montreal.
As part of Pearson Airport's temperature screening protocols, passengers will be turned back if their results are "elevated," unless they have proof of a specific medical or physical condition.
[Passengers] will not be permitted to continue their travel and will be asked to re-book after 14 days."
Temperature checks are already a mandatory procedure for airlines transporting passengers from outside the country.
Carriers like Air Canada have extensive health-related questionnaires to determine their passengers' fitness to fly.
As of September, 11 other busy airports in Canada will begin mandatory temperature screenings. These include Toronto's Billy Bishop, Edmonton, Saskatoon, Winnipeg, Regina, Kelowna and four others.
