First time H1b stamping!!???

Hi, I got my H1B approval last year in 2020. I was thinking about travel to my home country (India) for stamping. But because of COVID-19. I didn't find any open slots and then there was travel ban. As its my first time getting h1b stamp. Can I go to Canada and get it stamped. I have Canada visitor visa. and also I am fully vaccinated.

Has anyone tried this !!??

I need some advice, cause once I leave country. Without stamp I won't be able to enter.
