Transport Canada said on Friday that all airline passengers would be required to wear a non-medical mask or face covering during travel to curb the spread of coronavirus.
The regulator said travellers must cover their mouth and nose during the boarding process and flights. The rule goes into effect at noon ET on Monday.
Air Canada, the country’s largest carrier, had previously recommended that customers wear a face-covering over their mouth and noses while onboard its flights.
The carrier said in a statement that passengers may bring their own face covering, which may include a cloth mask, scarf or similar item. It added they would be asked to lower their masks for security checks.
