The best source of information on the population status of Orange-crowned Warbler in Canada is the Breeding Bird Survey (BBS). The BBS offers moderate coverage of the Orange-crowned Warbler's breeding range, with lower coverage in the northern extent of the range, but has high precision. BBS data show population growth from the late 1970s to mid-1990s, then relatively little change ever since; overall the national population has undergone a moderate increase of 66% relative to 1970. At a regional level, there have been moderate increases in the Prairies, Rockies, and southeastern British Columbia, but a large decrease along the Pacific Coast, and little change in the Great Basin area of British Columbia.  

The goal for Orange-crowned Warbler is to remain at or above its recent population level, based on the Breeding Bird Survey. Trend data show that Orange-crowned Warbler is currently within its goal range.
