The penalty for refusing to comply with Canada's hotel quarantine rules has just been boosted to $5,000, with the new fine set to come into effect on Friday.

This means air passengers who refuse to comply with the mandatory hotel stay will be subject to a $5,000 penalty, which is up from the previous fine of $3,000.

The larger fines will impact all international air passengers who attempt to avoid or bypass the current mandatory hotel stay.

The Government of Canada warns travellers that "The Contraventions Act provides police (including RCMP, provincial and local police) the authority to enforce the Quarantine Act."

Violating any of Canada's travel rules under this act could lead to fines up to $750,000 or even six months in prison.

Canada's borders remain closed to all non-essential international travel until at least June 21, 2021.
