Two people have been fined thousands of dollars after federal officials allege they showed altered COVID-19 test results before boarding flights to Toronto.

Transport Canada says one passenger was fined $6,500 for allegedly presenting an altered test before flying from the Dominican Republic on Feb. 8.

It says that passenger also made a false declaration to the air carrier about their health status.

The agency alleges another passenger was fined $2,500 for allegedly presenting an altered test before a flight from the United States on April 3.

The government requires air travellers to obtain a negative result on a molecular COVID-19 test within 72 hours of boarding a flight to Canada.

Airlines are instructed to refuse boarding to travellers who fail to meet that condition.
