The Canadian population of Baltimore Oriole is monitored best by the Breeding Bird Survey (BBS), which samples most of the breeding range, is well-suited to detecting the species, and has high precision. The national trend shows a moderate increase from the early 1970s to early 1980s followed by a steep decline to around 2010, and then a slight rebound to around 2000 levels, nearly 50% below its abundance in the early 1970s. The recent increase has been most pronounced in the Prairies, and to a lesser extent in southern Ontario and Quebec, whereas in the Maritimes the population decline has continued.

The goal for Baltimore Oriole is to increase the population to the level it was at in the early 1970s, based on the Breeding Bird Survey. Trend data show that Baltimore Oriole is currently below its goal range, but it has shown an increase over the past decade. Analysis of recent trends and potential growth rates suggests that Baltimore Oriole could reach its population goal by 2050 with the support of conservation action.
