Regarding the shoveling of sidewalks we should all be glad we don't live in these cities that get way more snow then we do. Windsor Ontario - Who removes the snow from sidewalks? Just a few that I found. Under City By-law 8544, the owners and/or tenants are required to remove snow or ice in front of their property within twelve (12) hours; owners or tenants of commercial properties have four (4) hours following the snowfall or formation of ice. Clear sidewalks are essential for many citizens especially those with disabilities, people who enjoy walking as form of exercise and children who walk to and from school. Snow covered sidewalks increase the likelihood of slip and fall accidents.
