Avalanche closure zones are back in Banff, Yoho and Kootenay national parks. They run from November 1, 2026 to May 30, 2027, and Parks Canada says they will be in effect on and off during that time.
The closures cover small, posted areas around designated avalanche paths. Staff trigger slides on purpose to protect roads and railways in the parks. Parks Canada says they use various tools for this, including remotely operated devices, so control work can happen any time of the day or night.
While a closure is on, the area is shut to all traffic and travel. Each one is generally short, about 24 to 36 hours.
How will you know? Permanent warning signs mark the affected areas in the field. Avalanche forecasters decide the timing, and Parks Canada says it will pass the word the day before through social media, avalanche bulletins and temporary closure signage.
It is worth taking seriously. Anyone who ignores a closure can be charged under the Canada National Parks Act, with a maximum penalty of $25,000.
For details on each of the Intermittent Avalanche Closure Zones in Banff, Yoho and Kootenay, see the closure zones page on the Parks Canada website. Check it, and the avalanche bulletins, before you head out this winter.
