Also, is it possible to for him to travel to Canada on a tourist visa while our application is being processed so he can be present during my labor?
First of all, congratulations for your pregnancy, Jenni! Do you know already if it is a boy or a girl?
And answering the question quoted, it is possible although can be hard in some cases. I am from a country who is required a visa to enter Canada... I submitted an application for a tourist visa at the Consulate and 2 weeks later I got the answer: visa approved. My husband and I were very honest and in our letters we were very clear about our intention to apply for sponsorship outside Canada and that we were just organizing everything to mail it to Mississauga, and what was the reason for me to travel to Canada. At the port of entry (customs) in Toronto, I told them the same, and I received 6 months to stay in the country after answering a few questions.
