Because cell phone service is very limited and unreliable in the backcountry of the Canadian Rockies, an option for GDT hikers is to use a satellite-based communication device such as a satellite phone, SPOT Messenger or Garmin inReach in case of emergency.
In case of emergency call 911.
When using a satellite phone, dialing 911 may connect you to an emergency centre unfamiliar with your geographic location so be prepared to provide your exact location to the dispatcher.
Parks Canada backcountry emergency numbers:
- Waterton Lakes National Park: 1-403-859-2636
- Banff, Kootenay, Yoho: 1-403-762-4506
- Jasper: 1-780-852-3100
Depending on your location, help may be a long time getting to you so be prepared to self-rescue and to keep yourself and your partners warm and sheltered during the time it takes for a rescue team to reach you.
