They seem to offer this - but don't specify what next, do I just mail in my passport to the canadian high commission in delhi for stamping?

There's a canadian foreign service strike going on so that applications on paper (such as through VFS) seem to be taking days on end. I read that online apps are going through much faster. Even spent ages scanning in 5 passports worth of entry and exit stamps, visas etc and uploading them + other documents onto the My CIC website.

I still haven't submitted yet .. because I came across one of those know it all "immigration forum" (immihelp type rubbish) where some guy claims this is only for people already in canada to submit fresh TRVs. What I read on my cic seems to suggest otherwise, but easier to ask first than regret it later.
