People use "widening" and "extension" interchangeably and the City does not. It is worth keeping them apart, because they engage different by-laws and one of them is currently paused.
| Widening | Extension | |
|---|---|---|
| What it means | Making the driveway wider, including the access at the curb | Extending the paved area further into your own property |
| Main rule | Access By-law No. 2026-139 plus Zoning By-law width caps | Zoning By-law No. 2026-50 — width, parking area and land use |
| Access permit | Yes, if the access changes | Not if nothing changes in the right of way |
| Usual sticking point | Width available on your frontage | Whether the new area counts as a front yard parking space |
The width cap still follows you
An extension does not escape the zoning width limits. Generally 6 metres in the downtown core and urban areas, 50% of the lot width elsewhere, and all accesses together capped at 50% of the frontage. If the extension makes the driveway wider at any point, the cap applies at that point.
Where extensions get complicated
Front yard parking permits are on hold. The Zoning By-law (No. 2026-50) permissions for creating new front yard parking spaces are not in effect until the Ontario Land Tribunal declares those regulations in effect. The City anticipated that happening by the end of September 2026. Until it does, the City cannot process a permit application to install or widen an access serving a new front yard parking space.
If that is your project, the sensible move is to get the design and quote settled now and file the moment the hold lifts — which also puts you in the queue for spring rather than at the back of it.
If your extension is simply a longer driveway or a pad behind the building line, it is usually straightforward. If it creates a new parking space in the front yard, you are in the paused territory above, and the City cannot currently process an application to install or widen an access serving it.

Drainage is the practical constraint
An extension adds impervious area in the part of the lot that drains toward your house and your neighbours. On a tight suburban lot this is the thing that actually decides the design. Options that work:
- Permeable pavement for the new area — a permitted surface, and rebate-eligible up to $5,000 in a Priority Stormwater Retrofit Area.
- A soakaway pit taking the runoff, rebated up to $2,500 on the same program.
- Grading the extension to a swale rather than to the property line.

Cost
Extensions tend to be the best value per square foot of any hardscape work, because the shape is usually simple, the access is good and there is no curb or culvert involved. Budget the same $18–30 per square foot installed, at the lower end for a plain rectangle. Full cost breakdown →
