The Deep Lake Water Cooling System or DLWC is a deep water source cooling project in Toronto, Canada. As a renewable energy project, it involves running cold water from Lake Ontario to air-conditioned buildings located in downtown Toronto.

The DLWC was built by Enwave, and opened August 17, 2004. Notable clients include Toronto-Dominion Centre, Royal Bank Plaza, RBC Centre, Metro Toronto Convention Centre, University Health Network, and Scotiabank Arena.[1][2]
