If a hospital is built near Dow's Lake, the Rideau Canal will lose designation as a UNESCO World Heritage Site.

Google: "Letter from UNESCO regarding inappropriate development -Rideau Canal." I am getting the impression that Parks Canada wants the property to be de-listed because they are privatizing it: "Parks Canada to look at divesting highways, bridges, dams - Cash-strapped agency examining whether to transfer or divest non-heritage assets worth $8.3 B." by Dean Beeby, CBC News, August 26, 2017.

The Rideau Canal has 52 dams, 47 locks, many bridges and a tunnel at Patterson Creek.
