I think you should move back home ASAP. Its probably hard not just for you, but her as well.
Also, if you really do feel the need to move her, then be diplomatic about it. Ask her how she feels about the matter and tell her that maybe it is better to live closer to family so she can get help and be around familiar people.
But honestly, you can't be punishing people due to your past traumas. You might not want to hear my advice, but most women would feel about resentful if they found out their husband was suspicious and was making life changing decisions based on his past experiences with another woman. Every man isn't the same, but every woman certainly isn't as well.
You'll screw your happy marriage if you're constantly on the look out for doom. Just put your trust in Allah and really consider quitting Canada for good, if you're not okay with bringing her to the west. Part time marriages long term isn't fair for either party, even more so for her as she needs a full time husband and a full time dad for her kids. She is essentially living the single mother lifestyle, but with regular money coming in. Not enjoyable whatsoever.
