In Canada, the Long-billed Curlew breeds in short-grass prairie and mixed, intermontane grasslands of British Columbia, Alberta and western Saskatchewan. It was once a common breeder in Manitoba, but is now considered extirpated from the province (Thompson 1891, COSEWIC 2002a). The most recent Breeding Bird Survey results suggest that the population in Canada has shown little overall change relative to 1970. However, the species was designated as Special Concern by the Committee on the Status of Endangered Wildlife in Canada in 2002 and reconfirmed as such in 2011 (COSEWIC 2011e, COSEWIC 2002a). The reasons for designation include historic and on-going habitat loss and fragmentation from conversion of native grasslands to agricultural crops, urban development and oil and gas, climate change and other factors. Long-billed Curlews also face significant threats from habitat loss on both the wintering grounds; ongoing conservation concern is warranted. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Historic declines were likely linked to market hunting, which largely eliminated Long-billed Curlews from migration stopover sites along the east coast of the United States. On the breeding grounds, historic loss of native grasslands led to declines in abundance of breeding birds, especially in the eastern half of the species' former range (Dugger and Dugger 2002). Habitat loss, both on the breeding and the wintering grounds, remains the largest current threat to the species' populations (COSEWIC 2002a) as native grasslands in Canada are lost to agriculture, development, and invasive species, and the wetlands and grasslands used by wintering birds face similar threats.

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:
