If you're in Canada on a valid work permit but don't have a current TRV, and need to travel to India for a family emergency:
- You don't need a TRV to travel to India itself — the visa requirement is for re-entering Canada, not for travelling to India.
- Apply for a new TRV as soon as possible, as an inland application from within Canada, before you leave. This lets you get it processed while your work permit is still valid, rather than trying to sort it out from abroad.
- Expect roughly 20 days of TRV processing time. Once approved, you complete the visa stamping in India before flying back to Canada.
The key point: don't leave Canada without first getting your TRV approved and stamped — travelling to India is fine, but re-entering Canada afterward requires a valid TRV in your passport.
