I am a Canadian citizen due to retire.  My retirement funds will make me struggle in Toronto,  Canada. I was considering Chiang Mai,Thailand for retirement. I  will be traveling to Chiang Mai with my wife, this December to check it out. However, I  have no idea of Visa that is required.
I would like to meet some expats in Ciang Mai when I  am there.
Can someone in this group guide me?
