(Gail Krantzberg, professor emeritus in McMaster’s W Booth School of Engineering Practice and Technology:) Trump’s suggestion about a faucet in B.C. should concern Canadians. It’s crucial that people start thinking about the potential impact of Trump’s policies on our water resources, not just in British Columbia, but across the entire continent. If he’s considering taking B.C.’s water to fight fires in California, what about our Great Lakes that support a $7 trillion economy? … The Great Lakes-St. Lawrence Sustainable Water Resources Act mandates that any water taken from the lakes must be returned, and it is only allowed for specific emergency purposes, like firefighting and drinking water. Pumping water back over long distances would be prohibitively expensive and difficult.
