Hello candidate,

First of all, if you are really into making an express to Canada and getting their geographical as well as social benefits then you can visit easily by PR Visa. With this Visa, anyone can live and work in another country.

Yes, you can join the merchant navy in Canada after completing graduation in B.tech from India from any branch. For joining merchant navy you need to do one year course Graduate Marine Engineering(GME) after your btech because it gives license to enter the merchant navy.

Hope this helps.

Good luck:)
