Absolutely correct! Many mea culpas. I need to remember not to post after writing 5 finals in 3 days on a combined 4 hours sleep. My sincerest apologies.
Do you want to know the most ironic thing of all ... ? My brother in law, is currently visiting us here in Vancouver ... and he has a multiple entry TRV that expires in three years (South African national)!
What I wanted to say (but obviously didn't come anywhere close to) is that the maximum length of a visit on a TRV (barring any later extension requests and approvals) is for six months, regardless whether the visa is one time or multiple entry. You may be permitted to make many many visits on a multiple entry visa, but each visit/stay cannot exceed 6 months in duration. My brother in law asked me how long he must be away from Canada between visits before "the clock resets to zero" and he can return for another period (up to 6 months) of time, but I was unable to give him a good answer. I simply told him that the whole topic is "a big grey area" and that nonoe really knows what the "official" stance is. It's all purely hypothetical as he's never stayed longer that 4 or 5 weeks at a time (he usually visits 2 to 3 times annually, mixing business with leisure catching up with his sis, aka. my wife, but it was a question that was both interesting to ponder and yet a bit disconcerting at the same time.
Again, my sincerest apologies for the completely incorrect info I posted!
Happy Holidays to all of you!
