Considering there is about a 200 word limit on a letter to the editor, I dont expect someone to write a thesis on how a major Canadian city should clean up its downtown, actually, it should be pretty straight forward. Get the street sweepers out early and fast starting first on our most frequented pathways like Jasper ave, bike lanes, and sidewalks (104 street?); have crews walk the downtown sidewalks cleaning up leftover gravel, dust, garbage (I have lived in downtown Montreal and Toronto and have frequently seen city crews doing this exact thing); have a crew every two weeks clean up blown garbage at our major entrance ways ie Gateway, Yellowhead, etc.
Source of funding? At least for the downtown portion - start with using the $1.5 million or whatever it was that is going towards replacing every speed limit sign from 50 km/h to 40 km/h and leave ridiculous make work WOKE projects like that for non-COVID times.
