As of February 29, 2024, at 11:30 p.m. Eastern time, Mexican citizens traveling to Canada will need to meet new requirements to travel to Canada.

Mexican citizens who hold a valid US non-immigrant visa or have held a Canadian visa in the past 10 years and are traveling by air on a Mexican passport will be able to apply for a new electronic travel authorization (eTA). With the high number of Mexican citizens currently holding US visas, the majority will continue to enjoy visa-free travel to Canada. Those who do not meet these conditions will need to apply for a Canadian visitor visa.
