I think when most people think about "getting married in Thailand" they think of a pristine beach setting ceremony bla bla bla...
Not having to go to MFA twice, run errands in hectic crazy hot Bangkok, to get a stamp here, another one there... get it translated, bla bla.
Yes, they can pay for these services.
As far as Canada, im not sure. But in the USA, upon return from your trip... your marital status is still SINGLE, unless u do the paperwork to register your marriage.
"They will accept your marriage certificate" is NOT the same as "your marital status has been updated on the records of the Canadian Government"
Personally I just think its a paperwork nightmare when you can just get married in the corner of your house and enjoy a "ceremony" here in Thailand which is what most people are after.
