The Canyon Wren is found in Canada only in extreme south-central British Columbia. The maximum spring population is approximately 100 pairs. Canyon Wrens require rock cliffs with deep crevices or slopes with very large-diameter boulders for foraging and nesting. They are non-migratory and can suffer catastrophic population declines during very severe winters, occasionally being temporarily extirpated from Canada. Habitat protection is adequate in British Columbia, but populations are low enough that the Canyon Wren should be considered Vulnerable.
