Since Garmin pay is not supported in Canada, can we ask you to ...

it is supported, it's just there are very few credit card providers that are signed up. you can find participating banks here Garmin International | Garmin Pay^™ Participating Banks

I really like your idea, but I think Garmin will say it's up to banks to support it. 

Did you do a suggestion on the Garmin suggestions area also as a catch all?

No I will do that, I work in integration and know it's possible.  Thank you for that, Ill do it.

Yeah that support is Narrow for Canada, and I dont want to change banks for my watch! ... I want my brain controlling my finances not wearables.  And intermediary like pay pal would solve that ... !! I have suggested the idea.

In the UK we have only a few banks supporting Garmin Pay. All I did was open an an account with one of them, set up a transfer from my regular bank to them and then I just transfer small amounts occasionally to the new account. Works really well, you don’t need to move bank, just set up an account.

I understand that, probably a poorly used term. But opening up and account elsewhere involves time, money and leads to fees.  It makes no sense.  It makes more sense to use payment gateways.  Thereafter there is no limit.  I think what you described is even MORE of a case for paypal support.

I set up a Starling account. Set up was via the app, very quick, free and no ongoing fees. It was a simple solution to the problem which meant Garmin don't have to spend time developing and testing a gateway. I doubt Garmin will fix this, but you could easily enable Garmin Pay on your watch. 

Startling is not a Canadian institution.  And enabling Garmin Pay wont help unless you have your bank to choose from.  Appreciate your replies.  But Garmin needs to thing more global in this area, not holes in the various countries they offer their product.  This payment issue in Canada can prevent sales.  I know it has.
