I believe they are also eligible for a similar card? As long as your parent or spouse are of Indian Origin (don't even have to be Citizens), you should have the ability to get that card?

I was reading up a bit and I think it's a mix of what you said and people who would be eligible for the OCI Forever-visa but never bothered getting it. I imagine many Indian-Canadians never visit India outside of a special occasion, and with the pandemic being over there's a uptick of these occasions.

Possibly a stupid question, but why are so many Canadians wanting to get an Indian Visa? Most of the people in the article look like they are of Indian Origin, would most of them not have an OCI card anyway?
