For temporary foreign workers (not to be confused with TFW program), you may be able to enter Canada if you meet specific requirements for your travel to be essential.
If you are normally a resident of Canada (e.g. you were just on vacation in India for a few weeks until the crisis), you can almost definitely return.
Otherwise, you will need your port of entry letter/letter of introduction and a confirmed job offer. You can ask CIC if you qualify (if you can get through to an agent, they are usually helpful.)
Travel restrictions and exemptions for temporary workers
As a temporary worker, you’re exempt from travel restrictions if
you’re coming for an essential (non-discretionary) purpose.
Certain people who can work without a permit may also be exempt from
travel restrictions. Essential (non-discretionary) travel for a
temporary worker
Essential refers to travel for reasons that are non-discretionary and
non-optional. The emergency orders under the Quarantine Act do not
allow people to travel to Canada for optional or discretionary
reasons, such as for tourism, recreation or entertainment.
As a worker, your travel is essential (non-discretionary) if you’re in
either of these situations:
- You have a valid work permit and normally live in Canada.
- This applies even if you’ve been laid off.
- You’re a worker who meets all of the following:
- has a letter of introduction for a work permit (open or employer-specific)
- has a valid job offer
- can work once you enter Canada and complete your 14-day quarantine (unless you’re exempt)
