My friend, In Toronto airport, You have to get your luggage from baggage claim belts and then go through custom area and then check-in like I described in my previous post! It is not possible that your international airline forward your luggage to your domestic airline because you have to pass custom at the port of entry. It is not important your next domestic flight be in the next hour or next 10 days. It is difference meaning of an international and a domestic flight. Because if your international inbound flight transfers your luggage to your domestic airline, there won't be any custom check at your destination in Sask because you are a domestic flight passenger!
I won't go through my scenario to stay in Toronto because I don't have any friend or family there. It was only a scenario and it is only a possible thing and I just trying to clear this situation that because of PNP immigration visa they can't and won't treat any pnp applicant like prisoner of Saskatchewan!!! :-X :-\
As a PNP applicant, all of us are equal to FSW new comers but we should start our life in our final destination in old beautiful Saskatchewan!
Good Luck.
