I just learned Toronto is Amsterdam's twin city. I had no idea...
There's little in Amsterdam to commemorate this bond, but I did walk across the Torontobrug earlier today. The Torontobrug (Bridge No. 350) is a link across the Amstel river between Amsteldijk and Weesperzijde. It has this plaque that references David Crombie, our mayor in 1974.
Fun fact: Toronto has a bridge called the Amsterdam Bridge with a similar plaque. The Amsterdam Bridge is a cable footbridge that crosses over the Simcoe Street Slip from York Quay to Rees Street Slip.
