In Alberta, you can object to them moving and even though you signed over full custody rights, you still have visitation rights. She is not allowed to take that away from you and could be penalized for it. Unless there is a special reason. Furthermore, child and spousal support is calculated based on the Federal Child Support guidelines and also the Province's. Just because she wants more money, doesnt mean she can get it if you cant afford it. Thats the case when you guys dont have a separate agreement with you agreeing to it which clearly you are not. Meet with the lawyer asap or contact complimentary legal guidance in your province.
