I think the OP is walking on very thin ice. Sure he could help but one whisper to the Thai police or immigration and he would be detained for not having a proper work permit.
That was what I thought. THAI consulate and mom's blessings and Thai passport and birth certificates and reams of paper work. Egad this means I will have to talk to the ex. The horror.
As a sidebar...once I get the affidavit the first time can I just use that each yearly visit or will immigration expect a newly dated one. The original approval will be the Thai consulate in Canada.
Tvc work in Thailand unreliable at best. I would never put one of daughters in a Thai production with the 30 percent commission and poor work conditions and then there is the issue about even getting the pay promised. Serve your time and don't worry about the tvc.
