As I mentioned before, this should be part of their sponsorship application in their native countries when they're applying. I'm sure there are interviews and other steps that are taken, but the integration should be an integration course or maybe an information session should be mandatory. They can be informed regarding Canadian values and rights, and also, as I said, employment opportunities because employment would make these women less vulnerable financially and it would also help them step out of isolation.
It would be a good idea to implement this in foreign embassies.
