The cost of extending a driveway in Ontario ranges from $4 to $30 per square foot, depending on the material you choose. A typical 200 square foot extension costs between $800 and $6,000 installed. Asphalt costs $4 to $10 per square foot. Concrete runs $9 to $18 per square foot. Interlock pavers are the most expensive at $18 to $30 per square foot.
These prices include materials, labor, base preparation, and basic grading. Removal of existing pavement, extensive drainage work, or difficult site access can increase costs by $1 to $4 per square foot.
Key Factors That Influence Driveway Extension Costs:
Material type — Asphalt, concrete, or interlock pavers
Extension size — Larger projects often get better per-square-foot pricing
Base preparation — Poor soil or drainage issues add $2 to $4 per square foot
Grading and slope — Proper drainage requires specific slopes away from buildings
Removal of existing surface — Adds $1 to $2 per square foot for demolition and disposal

Asphalt is the most popular driveway material in Ontario. The installed cost typically ranges from $4 to $10 per square foot in 2026. A 200 square foot extension costs $800 to $2,000. Prices vary based on oil market fluctuations since asphalt is petroleum-based.
Installation takes 2 to 3 days. The material needs 24 to 48 hours to cure before you can drive on it. Asphalt must be sealed every 2 to 4 years to maintain its lifespan.
Pros
Lower upfront cost than concrete or interlock
Quick installation compared to other materials
Flexible material handles Ontario freeze-thaw cycles well
Easy to patch and repair small cracks
Can resurface over existing asphalt to extend life
Snow removal is easier on smooth asphalt
Cons
Requires sealing every 2 to 4 years for maintenance

Concrete costs $9 to $18 per square foot installed in Ontario. A 200 square foot extension runs $1,800 to $3,600. Plain gray concrete is at the lower end. Stamped, colored, or exposed aggregate finishes push costs to $15 to $22 per square foot.
Installation takes 5 to 7 days including curing time. You need to wait at least 7 days before driving on new concrete. The material reaches full strength after 28 days.
General Ontario Requirements for Driveway Extensions
Driveway construction in Ontario falls under municipal jurisdiction. The Ontario Building Code does not specifically regulate residential driveway construction. Municipal bylaws control driveway dimensions, materials, and permits.
Construction Hours
Most Ontario municipalities restrict construction noise in residential areas. Typical permitted hours are:
Monday to Friday: 7:00 AM to 7:00 PM
Saturday: 9:00 AM to 7:00 PM
Sunday and holidays: Often restricted or 9:00 AM to 7:00 PM
Toronto allows construction from 7:30 AM to 7:00 PM on weekdays and 9:00 AM to 7:00 PM on Saturdays. Some municipalities ban construction on Sundays. Check your local noise bylaw before scheduling work.
Provincial Standards
Ontario regulations require proper drainage away from buildings. Driveways must slope away from the home at a minimum grade to prevent water from pooling near foundations. Most municipalities require slopes between 1% and 2% for proper drainage.
Ontario Municipal Driveway Bylaws and Permit Requirements
Driveway widening does not require a building permit in Toronto. Zoning bylaws limit driveway width based on lot frontage. The minimum driveway entrance width is 3.0 meters. Maximum width depends on your property’s zoning designation and lot width.
A street work permit is required if you work on the boulevard or need a curb cut. The permit costs approximately $130 to $200. Zoning restrictions may limit how much hard surface coverage you can have in your front yard.
Driveway width limits depend on lot frontage in Mississauga. For lots under 18.0 meters wide, maximum driveway width is 6.0 meters for a double-car driveway. Lots 18.0 meters or wider can have driveways up to 8.5 meters wide, increasing to 10.5 meters within 6.0 meters of the street.
Check the city’s Property and Zoning Information Map before extending your driveway. Minimum soft landscaping requirements apply to front yards.
Driveway work on private property is regulated by Oakville’s zoning bylaw. A Development Engineering Permit is required if you are widening the driveway entrance, installing a new curb cut, or changing drainage patterns. Repaving without changing the surface area does not require a permit.
Driveway width is limited by lot frontage. The standard culvert entrance is 6 meters wide for residential properties.
Burlington requires a driveway permit before constructing a new driveway or widening an existing one. The city updated bylaws in 2023 to control driveway expansion and preserve green space. Driveway width cannot exceed 50% of lot frontage or 8.0 meters, whichever is less.
Milton regulates driveways through zoning bylaws. Width restrictions are based on garage door openings and lot dimensions. Contact the town’s zoning services for specific requirements on your property.
Vaughan’s Zoning By-law 1-88 and Zoning By-law 001-2021 regulate driveway widths and curb cuts. The specific width allowed depends on your property’s zoning and lot frontage. Check with the city before beginning work.
Markham restricts driveway extensions based on lot size. Lots less than 10.1 meters (33 feet 4 inches) wide have stricter extension limits. Contact the by-law department to confirm what is allowed on your property before starting work.
Richmond Hill controls front yard parking and driveway widths through zoning bylaws. Maximum driveway width varies based on lot characteristics. Corner lots and irregular-shaped lots have specific rules.
A building permit is not required to widen a driveway in Newmarket. Zoning regulations may impose restrictions on width and location. Contact the Zoning Examiner to confirm compliance before proceeding.
Aurora regulates driveway construction through municipal bylaws. Check with the town’s planning department for specific width restrictions and permit requirements.
Durham Region municipalities (Ajax, Pickering, Oshawa, Whitby) each regulate driveways through their own bylaws.
Ajax: Does not have strict rules prohibiting parking on the boulevard portion of driveways. Standard municipal requirements apply to driveway construction and width.
Pickering: Allows extended driveways subject to zoning bylaws. Interlocking stone extensions may not require permits, while asphalt expansions typically do. Confirm with the city before starting work.
Oshawa: Traffic and Parking Bylaw regulates driveways. Parking on the boulevard portion is restricted in some areas. Standard width and construction requirements apply.
Whitby: Regulates driveways through municipal bylaws. Road permits are required for certain types of driveway work. Check with the town for specific requirements.
Clarington requires a Road Entrance Permit for driveway construction. The municipality regulates entrance construction to ensure proper installation and safe road operation.
Hamilton limits driveway width to 50% of lot width or 8.0 meters, whichever is less. Single-wide driveway approaches are 2.7 to 3.6 meters wide. Double-wide approaches are 5.4 to 6.1 meters. A driveway permit costs a minimum of $227 plus a $1,000 indemnification charge as of 2023.
Properties must maintain 50% green space in the front yard. The driveway must be at least 3 feet from fire hydrants and utility poles.
Drainage and Grading Considerations
Proper drainage is critical for any driveway extension. Water must flow away from your home and neighboring properties. Poor drainage causes foundation damage, basement flooding, and premature driveway failure.
Driveways need a minimum slope of 1% to 2% to shed water effectively. Steeper slopes work better but can create ice hazards in winter. The driveway should slope away from the house and toward the street or a drainage swale.
Base preparation is the most important factor for long-term durability. A proper base consists of 4 to 8 inches of compacted granular material (clear stone). Poor base prep leads to settling, cracking, and water pooling.
Sites with clay soil, high water tables, or poor drainage need extra base material and possibly drainage pipes. This adds $2 to $4 per square foot to the total cost. Skipping proper base prep saves money initially but causes expensive problems within a few years.
If your property has drainage issues, consider hiring an engineer or land surveyor to prepare a grading plan. Some municipalities require professional grading plans for projects that alter drainage patterns.
