As Torontonians negotiated snowy and icy sidewalks this past week, some were no doubt reminded of the problems the city had last winter with clearing sidewalks. One of them was the Toronto Star’s entertainment columnist Antonia Zerbisias, who took a break from her usual topics to write a nice summary of the problem in today’s paper. Among other things, she points out how damaging the alternative — lots of salt — is to the environment of a city that is in the midst of implementing a “green agenda”. After the flak the city took last year, it promised to improve its sidewalk clearance this winter. We’ll be keeping an eye out to see how that works out.
