If she had a tourist visa would it be legal to stay in Canada while the application is in progress or only until the 6 months is up on the time limited to tourists and then she would have to return to her country?
If you applied outland, you would need to apply for an extension on the visa, and from what I've read on these boards, if the application is in process, there is a high approval rate for extensions. It is recommended to apply for the extension at least 1 month prior to the visa expiry date. It's not recommended she stay beyond the allowed time on the visa. That can cause significant problems. For example, if she stays beyond the time listed on the visa, when she leaves and tries to come back, she can be denied entry. I'm not sure about how it affects applications, though i'm sure it's not helpful.
If you apply inland, i believe that's a whole different story. there are threads about inland and staying while the application is in process.
