A flood control dam was built on the West Branch of the Humber River immediately south of the village in 1957, creating the Claireville reservoir and the establishment of Claireville Conservation Area. Claireville began to lose it's rural character as suburban industrial development encroached. In the mid-1980, Albion Road and Steeles Avenue were realigned, bypassing the community. In the 1970s Highway 427 was built along the Indian Line alignment along the southwestern edge of the neighbourhood and in the 1990s was extended to Highway 407 when that toll road was built just to the north. This combined with the existing rail lines and proximity to Pearson Airport make the area prime industrial land. Today, some of original residential homes have disappeared in the Toronto section of Claireville and replaced with warehousing and open storage / trucking uses, and most of the remaining homes are no longer used as residences.
