Hey there! If you are traveling from Ireland to Canada, using a travel card like Wise or Revolut is by far the most convenient and cost-effective approach. You avoid steep bank conversion fees and can hold CAD directly in your app. Card payments are accepted almost everywhere across Canada, from coffee shops to public transport, so carrying large amounts of cash isn't necessary. If you want to check out current exchange rates, currency history, and transfer options, take a look at https://znaki.fm/ie-en/currencies/canadian-dollar/ this guide to the Canadian Dollar for helpful details. My personal recommendation is to carry just a small amount of cash for emergency tips or small local markets, but rely on tap-to-pay for almost everything else.
