The Canadian population of Redhead is at least moderately well monitored by three programs. The Waterfowl Breeding Population and Habitat Survey (WBPHS) is considered to be most representative, as it is designed specifically for waterfowl, provides good coverage of the population, and has high precision. The Breeding Bird Survey (BBS) has similarly high overall reliability. The continental Christmas Bird Count results also provide high coverage, but reliability is medium because of intermediate precision in the trends. The WBPHS and CBC agree that there has been a moderate increase in abundance of 61% and 53%, respectively, relative to 1970; the BBS trend shows a cumulative increase of 113%, just above the threshold of a large increase.

The goal for Redhead is to maintain a population of at least 490,000 individuals in the region covered by the Waterfowl Breeding Population and Habitat Survey. This is based on the North American Waterfowl Management Plan's goal of 701,000 individuals across the survey's full range, but adjusted to reflect the average proportion of the breeding population in Canada (69%). Data from the Canadian portion of the range indicate that Redhead is currently within its goal range.
