Thaha,

People do mistakes in life and who am I to tell you to do this and that...........but I  have seen 100's of  situations where wife forgave husband for what they did in past. And things went smoother in long run.You both are getting older day by day...what you would have thought was 100% right 4 years back, could be what a stupid idea I was thinking.........now!. I am seen too many of relationship like that...but mostly forgiven by women.

Your wife may have realised her mistakes, she could have improved. Even if you did inform canadian immigration regarding her issues...........I would still advise you to have a good talk with her when you go to Nepal. See what she has to say. Don't take too much negative feelings for her. Looks at her situation and see where she stands right now.

Your scenario may be different, but often nepali guys have a tendency of thinking new wife and new life...but it doesnot happen like that. Your son will be a step son for your new wife no matter what you say. And because you have gone thru divorce before you will keep on agreeing on things that your new wife has to say............trust me you will have insecurity feeling at this time too! Your new wife will have advantage towards you being a devorced man.

Talk to her and see if it is right step. Don't remarry until you are absolutely SURE!
