What is the process for applying for a DTV visa in Thailand for medical treatment from Canada?

The initial query inquired about applying for a Non-Immigrant D Visa for Medical Purposes (DTV) from Canada, specifically whether a consultation appointment at Bumrungrad International Hospital would suffice or if a detailed treatment plan was necessary. The responses suggested that documentation of a complete treatment plan is typically required, though some individuals shared their experiences of successfully applying with just consultation appointments and payment receipts. Additionally, one commenter pointed out the option of entering Thailand on a visa-exempt basis for consultations before applying for the DTV elsewhere.
