On your return, currently all travellers entering Canada by air or land require a pre-entry COVID-19 PCR test, are required to provide their basic contact information and ArriveCAN receipt, as well as undergo a COVID-19 test by a border services or quarantine officer on arrival.
Unvaccinated travellers arriving by land or air, you will be allowed to enter but will be required to isolate for 3 nights at a government hotel at their expense, followed by home quarantine for the remainder of 14 days. You must be able to use private transportation to get to your place of isolation and you must wear a non-medical mask while traveling to your place of isolation. You may not isolate in a place where you would have contact with medically vulnerable people such as people 65 years of age or older or people with underlying medical conditions. If you do not have private transportation or a suitable location to isolate, the Chief Public Health Officer of Canada will designate a facility for you.
Fully vaccinated Canadians (14 days after second dose) are exempt from the government hotel stay and will be released from quarantine once a negative test result is received. More information is available at https://travel.gc.ca/travel-covid
