Booking from U.S. via credit card

I'm looking at booking train 652 from Toronto to Montreal on viarail.com. The price comes out to be CAD$: $74.90. If I book this trip with my credit card (from the U.S.), will the 74.90 be automatically converted to US dollars?

Thanks in advance.

Yes. The bank will automatically convert the charge to U.S. dollars at the going rate of the day. Enjoy your trip on VIA.

OK...thanks, I appreciated it. So my trip will come out to around 60 U.S. bucks.
