After significant floods have swept through parts of Toronto three years in a row, washing out roadways, subway lines and basements, the idea of a stormwater charge is back on the table. The city staff proposal to make property owners pay for water runoff and the required infrastructure upgrades to deal with it was shut down by Mayor John Tory in 2017, when his executive committee sent it back to staff for more work. Giorgio Mammoliti, who was on council at the time, had incorrectly branded the charge as a "roof tax" that spurred opposition and Tory compared implementing the plan to trying to "unscramble an egg."
