If you're travelling by plane, there are some new measures in effect to know about. Temperature screening in Canada is now happening at four major airports in the country and more will follow. You can be denied boarding for more than just a high temperature too and here's what to do if that happens.

Canada has introduced mandatory temperature checks for all passengers travelling into the country or departing from airports here for domestic, U.S. and international destinations.

Departure checks came into effect at Vancouver International, Calgary International, Toronto Pearson and Montreal-Trudeau International on July 30.

If you have a temperature of 38 C or higher and don't have a medical certificate to explain a condition that would cause a high temperature then you won't be able to board.

You also won't be able to travel for 14 days after that.

If your temperature is high, a second check can be done as well to make sure it's accurate.

You'll also be denied boarding if you're symptomatic, have been turned away in the past 14 days because of something related to COVID-19 or if you're under a public health order.

That also applies if you refuse to answer questions for the health check, refuse to have your temperature taken or refuse to comply with wearing a face covering.

If you give a false or misleading declaration, you could face a fine of up to $5,000.

If you're denied boarding because of COVID-19 symptoms, Transport Canada has outlined what you need to do.

You should go somewhere you can self-isolate for 14 days right away and not use public transportation to get there.

Additionally, you should stay two metres away from other people.

It's also recommended that you frequently wash your hands, cough or sneeze into your elbow or a tissue and wear a face covering.

You can contact the airline you were travelling with about rebooking your flight for a later date.

By the end of September, screenings will be introduced at even more air travel hubs across the country.

Checks will be done at Edmonton, Halifax, Kelowna, Ottawa, Quebec City, Regina, Saskatoon, St. John's, Toronto Billy Bishop, Victoria and Winnipeg airports.

While air travel is nowhere near normal, carriers are offering reduced schedules to domestic and international destinations.

Air Transat started flying again after almost four months of planes being grounded.

WestJet and Air Canada are operating their summer schedules that are reduced from last year.
