In Canada, applying before visiting, how soon before my planned departure can I apply?
TLDR : Answer Summary
When applying for a Thai visa from Canada, it is advisable to submit your application 30-90 days before your planned departure. Tourist visas, typically valid for 90 days from issuance, should ideally be requested 3 months in advance, but applying 30-45 days prior may offer better flexibility for adjusting travel plans. For shorter stays of less than 30 days, a visa may not be necessary for travelers from certain countries due to visa exemption policies. The processing time can vary, with some applicants experiencing delays, so it's prudent to allow sufficient lead time.
