Keep Your Catch Basins Clear
Catch basins are critical for stormwater drainage, especially when snow begins to melt. Help prevent flooding by keeping catch basins free of snow, twigs, leaves and debris, when safe to do so.
Stay Safe Around Stormwater Ponds
These ponds are not for recreational use. NEVER skate, walk on, or play near them.
The ice is often thin and unstable. Stay back as shorelines are slippery and water levels can rise quickly, especially when snow and ice melt.
Stay safe by staying on Markham's designated trails when walking near stormwater ponds.
