The Canadian population of Hooded Warbler is small and poorly monitored. The continental Breeding Bird Survey (BBS) trend shows a largely consistent population increase since the early 1980s, with the population having more than doubled since 1970, but there is insufficient BBS coverage in Canada to determine a national trend. A northward expansion of range was documented between the first and second editions of the Atlas of Breeding Birds of Ontario, as well as by targeted surveys of the species between 1997 and 2007 which indicated a population increase of over 300% (COSEWIC, 2012). Although more recent evidence is limited, the consistent signals from available data lend high confidence to the conclusion of a large increase in the Canadian population relative to 1970.

The goal for Hooded Warbler is to remain at or above its recent population level. Resumption of targeted surveys may be required to evaluate this goal in future. Hooded Warbler is currently within its goal range.
