My sister is marrying a Canadian this year and wants to move to Canada very soon for lots of reasons. Usually, US citizens don't need a visa or even an eTA to enter and stay in Canada. The visa-free period is 6 months, but my sister is in a situation where she might need to be able to stay longer until she can get proper residence through a spousal visa, since the processing time for those currently sits at 10 months. Moving back temporarily is not an option, neither is waiting to move. As I understand it, you can apply to extend visitor visas, but that might not be the case for visa-free stays? We genuinely don't know where to get started looking.

Has anyone here done this, or been in a similar situation? Anyone who's immigrated through marriage and have had to figure out their stay like this, especially where it's not quite gone according to plan? Any and all suggestions and stories are welcome, we're all just 20-somethings navigating tremendous life changes without guard rails.
