While my heart goes out to any parent that is going through this, my heart goes out more to the child. You don't say if your other child is there also or is this child withdrawn not only from you but her sibling.
Also if you have a court order visitation in Canada as well as here, You need to get the paperwork in order and the "WILL" enforce it and to my knowledge it doesn't take any 6 months to a year. You don't have to go to court again you already have the paperwork done.

IF the paperwork names you as the custodial parent, then they have no choice but to enforce the court order.

I also have to agree I think there is way more to the story that is what portrayed here.

I also notice the OP hasn't come back in for along long time.
