It’s weaker than let’s say Pound Sterling or the Euro for example. But, does a weak CAD affect international travel towards Canadian travelers? Since they’ll be paying more whilst abroad requiring CAD in higher amounts to exchange for larger sums of cash (like if 1000€ = C$1617 that alone is a steep hike while C$1000 = 618€ see the difference?). Also, when you travel: do you bring CAD or exchange for USD first prior due to that having a better exchange rate?
Using MasterCard/VISA are easier for the sake of not getting robbed.
I would exchange for the destination currency at a bank before traveling if I needed cash.
