June to August is Canada’s bonanza season, or to be more specific, Victoria Day (late May) to Labour Day (first weekend in September). Sunny weather, snow-free landscapes, and long hours of daylight (the sun barely sets in the far north) conspire to pull in foreign tourists and huge domestic crowds. Satisfying the demand, everything is open, from museums to hiking trails to wildlife excursions. Even winter ski resorts convert themselves into summer hiking and biking destinations. Summer caveats include higher prices (count on paying 30% more), busier facilities, and more limited availability. Book ahead and come armed with a variety of options.
