Can You Enter Canada on a US Visa if Your Country Is Free?

No, it is not possible to enter Canada on a U.S. tourist visa. The visa requirements for Canada and the U.S. are separate and distinct. If your country does not require visas for Canadian citizens, this does not automatically grant you entry into Canada on a U.S. tourist visa. You will need to check Canada's specific entry requirements for citizens of your country and obtain the appropriate visa or Electronic Travel Authorization (eTA) if required.
