Transit through Vancouver International (Round trip US-India-US)

Question

I would like to fly round-trip from USA to India via Vancouver International and back, on a flight operated by Air Canada (code sharing with United Airlines) in Oct-Nov 2019. I hold a passport from India and a valid multiple entry Canadian Visitor's visa.

1. Would I also need to apply for a Canadian Transit Visa in addition to the Canadian Multiple entry Visitor's visa I already have in order to transit via YVR (layover less than 48 hours)? Or is the Canadian Multiple entry Visitor's visa enough for the transit?
2. Is a layover time of 1h 35m typically enough to go through Canadian immigration at YVR and board the onwards Air Canada flight back to USA?

Thanks

Answer 1

Your existing temporary resident visa is fine for entering Canada. You don't need a second temporary resident visa just to transit. And you have enough time between your flights.
