if you want visa while in Thailand and you are Canadian they say to get done in Bangkok everything is theee that you will need and have your money and bank statements ready when you open a bank account , good luck
I got married in Thailand on vacation did not need visa , came back to Canada got my wife a visa for Canada and when she here apply for permanent resident visa so she can travel here anytime and I’m in a retirement visa so I cannot ever travel back and forth multiple times , there , now you know , just phone Thai consulate in Vancouver they will help you with online application with E-Visa and give you all your options
yes I gave him Canada version once her married and comes back to Canada to get his business in order and apply for visa in Vancouver and get approved then happy journeys
