Travellers to Canada or those transiting through, here's authorisation you may need

Canada's immigration authority has revised its entry requirements for foreign travelers. Visitors may now need an electronic travel authorization (eTA) or a visa to enter the country. Citizens from eligible nations using air travel are required to secure an eTA. Additionally, US citizens and green card holders must adhere to specific entry regulations. It's essential for all travelers to meet fundamental health and financial criteria upon arrival.
