Police said they went to assist the Canada Border Services Agency (CBSA) at the airport Monday evening.
Police said a CBSA officer and a quarantine officer were conducting checks at an inspection point and a man’s negative COVID-19 test document “was revealed to be fraudulent.”
Police said the man actually tested positive for the coronavirus and was subsequently arrested and charged for unlawfully using a forged document.
Officers and public health officials “determined that there were no additional offences” under health regulations, police said, and the 29-year-old Stratford man went to a hotel for quarantine.
He’s scheduled to appear in court to face the charge on April 19.
Canada currently requires international travellers coming to the country to present a negative COVID-19 test before boarding a flight.
The Ontario government also requires travellers at Pearson Airport to take a second COVID-19 test once arriving.
