Do You Need a Permit for a Concrete Driveway in Ontario?
Updated October 2026
Driveway rules are set by your municipality, so the answer depends on your address. Clarington requires a permit to cut a curb or widen a driveway entrance, and Oakville requires one to install or alter a driveway in the municipal right-of-way. The only reliable answer is a call to your municipality before the pour.
“Do I need a permit?” is one of the first questions homeowners ask before a new driveway. The honest answer is that Your municipality sets the rules, and they differ from town to town. We are a concrete company, not your city hall, so this guide shows what three municipalities publish and what to ask your own.
The short answer
Two questions help you find out whether you need the city’s approval:
- Does the work touch the city’s land? Work on the curb, a culvert or the road right-of-way is what the municipalities below regulate.
- Is the driveway new or wider? Adding a driveway or widening one is treated differently from replacing a driveway in the same place.
Work on the city boulevard and curb
Clarington requires a private entrance permit to cut a curb, widen a driveway or install or replace a culvert, and treats curb cuts or widenings done without one as illegal. Oakville makes permits mandatory for any installation or alteration of a driveway within the municipal right-of-way; its published procedure exempts resurfacing an existing apron without additional alteration. Fort Erie notes that work in the public right-of-way must be done by a contractor hired by the property owner.
Other towns have their own rules. Whatever the permit is called, ask the same question: does any of this work touch the curb, a culvert or the road right-of-way?
Replacing a driveway in the same place
If you are taking out an old slab and pouring a new one in the same footprint, ask your municipality whether the curb, the apron at the road or a culvert will be touched. Oakville, for one, exempts resurfacing an existing apron without further alteration. If the old driveway has to come out first, our concrete removal and demolition work is part of the same plan, and we price it in the same written quote.
What to ask your municipality
Call or check the city’s website with your address, and ask:
- Do I need a permit or approval for a new, wider or replaced driveway at my address?
- Is there a maximum width for a driveway at my address?
- Does anything in the boulevard, curb or culvert need separate approval?
- Who applies, me or the contractor, and how long does approval take?
- Is there an inspection, and when?
Write down who you spoke to and what they said. If your plans change, ask again.
Why it matters before the pour
Concrete is hard to undo. Clarington, for one, treats work done without a required permit as illegal, and redoing a new slab means paying for the work twice. A phone call costs nothing and happens before the base is dug.

Do I need a permit to replace my existing concrete driveway?
It depends on the municipality and on what changes. Oakville requires a permit to install or alter a driveway in the municipal right-of-way, but its published procedure exempts resurfacing an existing apron without further alteration. Clarington requires a permit to cut a curb or widen an entrance. Call your municipality before work starts and ask about your address.
Do I need approval to widen my driveway?
In Clarington you must apply for a private entrance permit to cut a curb or widen a driveway. Other municipalities have their own rules. Ask before you book the pour.
Who applies for the permit, the homeowner or the contractor?
It varies by municipality and by permit. Ask the city who has to apply. Some work in the public right-of-way must be done by a contractor hired by the property owner. We will tell you what we need for your quote, and the city confirms what it needs for your address.
Can the city make me remove a driveway built without approval?
Clarington treats curb cuts and driveway entrance widenings done without a permit as illegal, and refers them to Municipal Law Enforcement. That is why it is worth checking before the pour, not after.
