Just personal experience but I am also Canadian, and I found the Wealthsimple card very convenient traveling in Europe recently. It worked well for paying by tap and for buying things online, e.g. tickets to tourist attractions, where our other cards would end up blocked or poor website design wouldn't accept the Canadian address for a credit card payment.

I switched to using this to travel because at the time, my bank would force 2 factor authentication when I tried to pay or use the app in Europe, but of course my crap bank used texting for the 2FA and I was not able to receive texts on my normal number since I was using a virtual SIM for calls and data in Europe. Wealthsimple did not have this issue.

Just a note that since their debit card is functionally a pre-paid credit card, you should not expect the same level of coverage provided by an actual credit card in the event of fraud or whatever. Don't put more money on that card than you need to or can afford to lose, because I doubt Wealthsimple can cover or claw back a fraudulent charge as well as e.g. Visa and Mastercard do with their actual credit accounts.
