Riding The Canadian: Testing the Canon RF 100–300mm f/2.8L IS - on a Transcontinental Journey

Travelling from Ottawa to Vancouver Island aboard VIA Rail’s legendary transcontinental route—The Canadian—is an experience that blends nostalgia, wilderness, and sheer geographic scale. Over two weeks, I crossed the entire breadth of the country with a rare opportunity in hand: a loaned Canon RF 100–300mm f/2.8L IS, one of Canon’s fastest and most versatile telephoto zooms. What better proving ground than a journey through six provinces, endless forests, prairies, mountains, and some of Canada’s most dramatic wildlife encounters?
