Canadian populations of Blue-winged Teal are at least moderately well monitored by three programs. The western population is best monitored by the Waterfowl Breeding Population Habitat Survey (WBPHS), which is highly suitable, covers much of the range, and has high precision. The national population is best tracked by the Breeding Bird Survey (BBS), which also has high suitability and precision but provides broader coverage of the overall Canadian breeding range. The Waterfowl Breeding Population Survey of the Central Interior Plateau of British Columbia (BCCPWBS) offers additional insights to part of the western population. The WBPHS indicates little change in abundance relative to 1970 (-9%), with the BBS showing similar results (-14%) over the same period. The BCCWPBS indicates a moderate increase of 56%, but over a much smaller area and shorter period, since only 2006. In eastern Canada, the majority of the population is in Central and Southern Ontario and Quebec and in the Maritimes, with large declines ranging from 84% to 96% since 1970 based on the BBS.

The national goal for Blue-winged Teal is to maintain its population at or above the level it was at in the early 1970s, based on the Breeding Bird Survey. Recent data show that the population is within its goal range.

The goal for the western population of Blue-winged Teal is to maintain a population of at least 3.1 million individuals within the area sampled by the Waterfowl Breeding Population and Habitat Survey. This is based on the North American Waterfowl Management Plan's goal of 4.949,000 individuals across the survey's full range, but adjusted to reflect the average proportion of the breeding population in Canada (57%). Data from the Canadian portion of the range indicate that Blue-winged Teal is currently within its goal range. 

The goal for the eastern population of Blue-winged Teal is to increase the population to the level it was at in the early 1970s, based on the Breeding Bird Survey for Bird Conservation Region 13. Trend data show that this population is far below its goal range and its decline is ongoing. The trend will need to stabilize before the population can begin to rebound, and it is not realistic for the goal to be met by 2050. Based on analysis of the historical population loss and potential growth rates, the interim target is to reach 25% of the goal by that year. Achieving this target, and ultimately reaching the national goal for this population, will require ambitious and long-term conservation action.
