The eTA, the distances, and the two languages

Visa-exempt visitors flying in need an Electronic Travel Authorization bought online for a few dollars before departure; apply on the official Government of Canada site, not a look-alike. Canada is enormous: Toronto to Vancouver takes five hours in the air, and even Montreal to Quebec City is three hours by train. In Quebec, French comes first; a "Bonjour" and a few words go a long way, though almost everyone in Montreal switches easily.
