Yes, current regulations under the emergency Quarantine Act require anyone returning to Canada from another country, with exemptions only for certain essential workers, to quarantine for 14 days. Of course, right now that means only Canadian citizens, since the country is closed to any non-essential travel by foreigners, with a few exceptions for immediate family members. Your quarantine plan must be approved by the border officer at the time of entry to Canada.

Quarantine is not the same as isolating-in-place, as we have done during the lockdown. Under the quarantine rules, you must go immediately and directly to your place of quarantine (which could be your normal home) and stay there for the full 14 days. You must have a plan that arranges for delivery or pre-stocking of any essentials, such as food, water and medicines. You may not leave your place of quarantine for ANY reason, nor even go outside, unless you have a balcony or private, enclosed backyard. Police and health officials typically do 2 or 3 checks during the quarantine period to ensure you are complying.
