The Blackpoll Warbler is widespread across the northern forested regions of Canada. Data are insufficient to determine its population status in Canada at this time. Available results from the Breeding Bird Survey suggest a large decrease in population since about 1970, but these results are not reliable due to poor coverage of the bulk of the breeding population, which is spread throughout the boreal forest. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Information on population trends for this species is lacking; more information to determine whether the suggested declines reflect the national population is needed. Although logging may introduce temporary disruption, habitat availability on both the wintering and breeding grounds appears to be generally unthreatened (DeLuca et al. 2013). However, increasing temperatures have caused the ecotone between the northern hardwood forest and montane spruce-fir forest to shift upward. If temperatures continue to increase, losses of high-elevation conifer habitat are predicted (DeLuca et al. 2013). Habitat loss may also occur along southern margins of the permafrost zone as tree cover loss due to the melting of permafrost may outweigh potential gains from post-fire regrowth (Helbig et al. 2016). The combination of Canada's high responsibility for the Blackpoll Warbler and poor survey coverage over much of its breeding range suggest that this species warrants extra attention.
Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
