Paul Van Wetten is a true Deadbeat Dad

Paul Van Wetten is a 47 year old man who was originally from Mississauga, Ontario. He is 5 feet 11 inches tall, with Graying curly brown hair, hazel eyes and a slim build. He has a scar on his leg from a skill saw accident. 3 years ago, he stopped phoning or visiting his 5 children. At that time they were 4, 7, 8, 10, and 15. One and a half years ago, he decided I guess that the children were self sufficient and didn't need him to support them anymore. He stopped paying any child support.
At some point, he moved to Calgary, Alberta to work in construction which he has done most of his adult life.
Unfortunately, he doesn't contact any member of his own family,(who have been very supportive) including his parents and 4 brothers or his 2 children, from a previous marriage. Although they are grown up and on their own, he doesn't realize or care that he is the grandfather of a 2 year old girl.
He wasn't always such a loser. Our son , who is now 11, had a twin brother. His twin had a heart condition which caused his death at 3 and a half weeks. On the day Paul saw him in the hospital, hooked up to a respirator and many tubes, Paul started to drink daily and never quit. I left him a year later.
For many years, he would pay on a regular basis. Eventually though, I felt it necessary to obtain a court order to ensure that I would continue to receive child support.
This is when he disappeared.
The laws in Ontario, do not let you obtain a court order from someone in Alberta, unless you have an address. Guys like this, do everything they can to make sure they don't have one available to the public. They move alot,, they live wherever they don't need to register an address and they move on again, especially if they think someone might be onto where they can be found.
I have done everything I can to track him, and keep failing.
I contacted our local M.P.'s office in Northern Ontario for possible resources and was told that I would have to get responsible for myself and move on.. I am as responsible as I can be, I have 2 jobs, and I take care of my kids and provide all that I can. Sometimes, this falls short of what they need. Even with 2 jobs, it is hard to make ends meet often.
I am of course, looking for any information that any one might have on this dead beat dad and if anyone has any way to track a dead beat that I'm missing, please email me.
