Assessment rationale/justification
This species is rarely reported in its Canadian range. There are, however, a few sites in the Okanagan Valley where they regularly can be captured during the summer. There is a lack of data about the extent of its Canadian range and the habitat that is important for foraging and roosting. We also do not know the population size or trends, nor any key demographic characteristics, such as population structure, reproduction or survival rates. It is not known if this species overwinters in Canada or migrates south for the winter; however, there are maternity colonies recorded in Canada.; Cette espèce est rarement observée dans son aire de répartition canadienne. Il existe cependant, quelques sites dans la vallée de l'Okanagan o๠l'espèce peut être régulièrement capturée en été. Il existe un manque de données sur l'étendue de son aire de répartition au Canada et sur l'habitat qui est important pour son alimentation et son repos. Nous ne connaissons pas non plus la taille ou les tendances de la population, ni les caractéristiques démographiques clés, telles que la structure de la population et les taux de reproduction ou de survie. Nous ne savons pas si cette espèce hiverne au Canada ou si elle migre vers le sud en hiver; cependant, des maternités coloniales ont été trouvées au Canada
