Does an Ottawa driveway repaver need a permit if dimensions stay the same?

Generally no, repaving an existing driveway with the same dimensions does not require a permit from the City of Ottawa. Routine resurfacing, asphalt overlay, or full tear-out and replacement that maintains the existing footprint and drainage patterns is considered maintenance rather than new construction.

Permit-free driveway work includes asphalt resurfacing (overlay), complete asphalt removal and replacement in the same location, sealcoating, crack repair, pothole patching, and interlock paver replacement or relevelling within the existing boundaries. The City of Ottawa treats these as maintenance activities that don't alter the property's impact on municipal infrastructure or drainage systems.

However, you will need a permit if the repaving work involves changing the driveway opening onto the municipal road, altering the curb cut, working within the road allowance (the area between your property line and the street), or modifying drainage patterns that affect stormwater flow. The driveway apron — the section between the sidewalk and road — sits within the municipal right-of-way and typically requires a permit and inspection even for replacement work.

Ottawa-specific considerations make proper repaving critical even without permits. The city's extreme freeze-thaw cycles (50+ per winter) and deep frost line (1.2 to 1.5 metres) mean that any repaving work must include adequate base preparation. Simply overlaying new asphalt over a failed base will result in reflection cracking and surface failure within 2-3 Ottawa winters. If your existing driveway shows signs of base failure — widespread cracking, settling, or heaving — full excavation and base replacement may be necessary, which still doesn't require a permit but demands professional expertise.

Before starting work, verify that your contractor carries WSIB coverage (mandatory in Ontario) and confirm the work stays within your property boundaries. While permits aren't required for same-dimension repaving, the work must still comply with City of Ottawa drainage requirements — water must flow away from your foundation and neighboring properties.

When to hire a professional: Asphalt paving requires specialized equipment (paving machine, vibratory roller, dump trucks) and precise temperature management of hot-mix asphalt. The narrow paving window in Ottawa (late May through September) and the need for proper compaction while the asphalt is still hot make this strictly professional work.
