Should I plow my Ottawa driveway after every snowfall?

No, you don't need to plow after every snowfall in Ottawa. For most homeowners, plowing after accumulations of 5-8 cm (2-3 inches) or more is sufficient, though this depends on your driveway material, household needs, and snow conditions.

Plowing frequency should match your driveway surface and usage patterns. Asphalt driveways handle regular plowing well once the surface has cured for at least one full season. New asphalt (less than 6 months old) should be plowed carefully to avoid gouging the softer surface. Interlock driveways require more caution — plow blades can catch raised or settled pavers, especially along edges where frost heaving is common. Set your plow blade slightly higher (about 1-2 cm off the surface) on interlock to avoid damage. Concrete driveways are the most plow-friendly surface but watch for control joints where the blade can catch.

Ottawa's snow patterns make strategic plowing more effective than frequent plowing. Our city typically receives snow in multiple waves throughout winter, often followed by chinook winds or mild spells that cause partial melting. Plowing light dustings (under 5 cm) can actually make your driveway more slippery by creating a thin ice layer when temperatures fluctuate around freezing. It's often better to let light snow accumulate until you have enough depth to plow effectively down to the surface.

Consider your household's daily needs and driveway slope. Steep driveways may need plowing after smaller accumulations to maintain safe access, especially if you have elderly residents or mobility concerns. Flat driveways can typically handle more accumulation before plowing becomes necessary. If someone in your household leaves for work at 6 AM daily, you'll need more frequent clearing than a household with flexible schedules.

Timing matters more than frequency in Ottawa's climate. Plow before heavy snowfalls compact into ice, especially when temperatures are forecast to rise above freezing then drop again. The freeze-thaw cycles that hit Ottawa 50+ times per winter turn packed snow into concrete-hard ice that's much harder to remove. If a major storm is forecast (15+ cm), consider plowing partway through rather than waiting for the full accumulation.

Protect your driveway surface during plowing. Use a rubber-edged blade or poly blade rather than a steel edge, especially on interlock and new asphalt. Mark driveway edges with reflective stakes before winter — Ottawa's snowbanks can hide driveway boundaries and landscaping. Avoid piling snow against your house foundation or over septic system components. Direct snow to areas where spring melt won't flow back onto the driveway or toward your foundation.

Alternative approaches work well for smaller driveways. Many Ottawa homeowners successfully use snow blowers for regular maintenance and only call a plow service for major storms over 15-20 cm. Snow blowers are gentler on interlock surfaces and give you more control around parked cars and landscaping. For very small driveways (under 30 square metres), a quality snow shovel and ice chopper may be sufficient for most snowfalls.

When to hire a professional: If your driveway is over 100 square metres, has complex curves or steep slopes, or you have physical limitations, a seasonal snow removal contract often provides better value than DIY plowing. Professional operators know how to work around different surface materials and can handle Ottawa's challenging ice conditions more safely.
