Parking Lot Repair & Asphalt Patching in Thunder Bay, ON

Pothole patching, crack sealing, catch basin repair, and resurfacing.

Freeze-thaw cycles make asphalt maintenance a recurring capital line for every Canadian commercial property. Crack sealing and patching in year 1–5 defers full resurfacing, which costs 10–20× more.

Thunder Bay carries a labour index of 1.00 against the national baseline, 76 snowfall days a year, and roughly 2,900 commercial buildings competing for operator capacity. Those three inputs move the asphalt repair band below more than any other local factor.

What asphalt repair costs in Thunder Bay

Property size	Low	High	Unit
Small	$900	$36,000	per project
Medium	$2,000	$80,000	per project
Large	$4,200	$168,000	per project

Compliance in Ontario

Confirm the operator is in good standing with the Ontario workplace safety board.
Request a certificate of insurance naming the property owner as additional insured.

What to check before signing

Is the repair hot-mix, cold-patch, or infrared — and is that appropriate for the season?
Are catch basins and drainage inspected as part of the quote?
What traffic-bearing cure time is quoted?

Frequently asked questions

When is patching enough vs. full resurfacing?

If less than ~25% of the surface shows distress, patching and crack sealing typically buys 3–7 years. Beyond that, resurfacing is usually cheaper per year of service life.
