as the Thai Embassy in Paris from field reports here in this Facebook Group and other Groups and Forums is known to be one of the slowest to process any Thai E–Visa Application among all of the 94 Thai Embassies/Thai Consulates around the world, the OP should be fine for a Non–O E–Visa as the validity of Single Entry Non–O or Single Entry Tourist Visa (SETV) E–Visa's is usually 90 Days and factor in over a full month for E–Visa Processing at the Thai Embassy in Paris and planned Entry Date into Thailand around 13 December 2025

FYI—

For anyone applying for any type of Thai E–Visa at any Thai Embassy/Thai Consulate around the world, but specifically for the Thai Embassy in London:

"...

All applicants must be residing within the UK/Ireland/UK territories when apply for the Visa. The Royal Thai Embassy has the right to cancel the visa applications should you fail to provide the evidence of your presence within the UK/Ireland/UK territories while applying for the visa.

Did you contact the LTR Visa Office to perhaps get a Certification/Confirmation Letter of sorts issued by the LTR Visa Office to bring with you to the bank?

Congratulations! Which (where) Thai Embassy/Thai Consulate did you apply for your DTV E–Visa??

Are you asking about obtaining a DTV Extension of Stay inside Thailand at a local Thai immigration office and whether that local Thai immigration office will accept your Canadian bank account??

if so, then which (where) local Thai immigration office are you going to get a DTV Extension at??

of course, as you are located in Canada NOW, then this potential question of obtaining a DTV Extension at a local Thai immigration office inside Thailand can only be pertinent 5 to 6 months after you make Entry into Thailand again....

FYI–

The OP has stated that they already have a DTV (E–Visa?), so this question is NOT about applying for a DTV E–Visa at any Thai Embassy/Thai Consulate, but applying for a DTV Extension of Stay at a local Thai immigration office inside Thailand at least 5–6 months AFTER they make Entry into Thailand again
