The Canadian population of Eastern Screech-Owl is monitored by both the Breeding Bird Survey (BBS) and the Christmas Bird Count (CBC). The BBS samples most of the Canadian breeding range, but is not well-suited for detecting owls, and precision of estimates is medium at best. The CBC largely samples the same population, but can include more focused effort on owl detection, and is likely to overall be more reliable for this species, although it may be somewhat vulnerable to increasing effort over time on detection of owls. Despite broad uncertainty around annual estimates, there is a clear increasing trend shown by both sources, with the CBC indicating a large increase of nearly 300% since the early 1970s, and the BBS trend showing a moderate increase of nearly 70% over the same period. Combined, there is high confidence that the population has increased by at least a moderate amount.

The goal for Eastern Screech-Owl is to remain at or above its recent population level, based on the Christmas Bird Count. Trend data show that Eastern Screech-Owl is currently within its goal range.
