How do I keep my Ottawa driveway clear during a heavy storm?

The key to managing your Ottawa driveway during heavy storms is staying ahead of accumulation with frequent clearing, using proper techniques that protect your surface, and having the right equipment ready before the storm hits.

Snow Removal Strategy for Ottawa Storms

Start clearing when you have 5 to 8 centimetres of accumulation rather than waiting for the storm to end. Ottawa's heavy, wet snow becomes exponentially harder to move as it deepens and compacts. Clearing every few hours during a major storm prevents the bottom layer from bonding to your driveway surface and forming that stubborn ice layer that damages asphalt sealcoat and catches plow blades on interlock pavers.

For asphalt driveways, use a plastic-bladed snow pusher or rubber-edged shovel to avoid gouging the surface, especially if it's been sealcoated. Metal shovels and snow pushers scrape away sealcoat and create grooves that collect water and accelerate freeze-thaw damage. If you're using a snowblower, adjust the skid shoes to leave about 5mm clearance above the asphalt surface. Never let the auger housing scrape directly on sealed asphalt.

Interlock and concrete driveways can handle metal-edged tools better, but be careful around raised or settled pavers that can catch shovel edges and plow blades. A snow pusher works better than a shovel on interlock because it glides over uneven pavers instead of catching edges. For both surfaces, push snow toward your lawn or designated snow storage area rather than piling it on the driveway where it creates drainage problems during thaw.

Equipment and Timing Considerations

A quality snow pusher with a 24-inch blade moves snow faster and with less back strain than a traditional shovel during heavy storms. For driveways longer than 30 metres or wider than a single car width, consider a single-stage electric snowblower — they're quieter than gas models (important for early morning clearing) and start reliably in Ottawa's cold temperatures without the carburetor issues that plague gas units.

Salt and ice management requires careful consideration of your driveway material. Rock salt works down to about -12°C, but damages concrete surfaces through scaling and accelerates oxidation in unsealed asphalt. Calcium chloride works to -25°C and is less damaging to concrete, while magnesium chloride is the gentlest option for new concrete (though more expensive). Sand provides traction without chemical damage but requires spring cleanup. Never use deicing chemicals on concrete driveways in their first winter — the surface hasn't fully cured and will spall.

During Ice Storms and Freezing Rain

Ottawa's notorious ice storms require a different approach. Don't attempt to chip thick ice buildup with metal tools — you'll damage your driveway surface. Instead, apply a small amount of ice melter to create initial melting, then use a plastic ice scraper or wait for temperatures to rise slightly. Focus on creating channels for drainage rather than removing all ice immediately. Standing water from rapid ice melt can refreeze into a more dangerous sheet if temperatures drop again.

Professional Snow Removal Services

For larger driveways or if you're frequently away during storms, professional snow removal services typically charge $300 to $800 per season for residential driveways in Ottawa, depending on size and frequency. Make sure any service you hire uses appropriate equipment for your driveway type — plow trucks with steel blades can destroy interlock edges and catch on settled pavers, while rubber-edged plows or snow pushers are safer for all surfaces.

The most critical factor is consistency — Ottawa storms can dump 20 to 40 centimetres in a few hours, and letting that accumulate makes clearing exponentially more difficult while increasing the risk of surface damage from heavy scraping and ice formation underneath.
