The larvae develop in temporary or semipermanent shaded woodland pools containing fallen leaves, and to a lesser extent in pools in small stream beds and pools and ditches adjacent to wooded areas. The species overwinters in the egg stage, and the larvae hatch in large numbers in the late winter and spring. it is seldom a troublesome biter in the eastern part of its range, even in areas where large numbers have recently emerged. In the western part of its range the females are persistent biters, attacking readily in shaded situations throughout most of the day. (Carpenter and LaCasse 1955:163 )

Medical Importance:
Ae. canadensis is considered a vector of eastern equine encephalitis (EEE) and West Nile Virus (WNV) (Turell et al. 2005:60)
