MTO Permits for Provincial Highways in Ontario
Comprehensive guide to Ministry of Transportation permits for properties adjacent to 400-series highways and King's Highways. Building permits, entrance permits, sign permits, and encroachment permits.
Do You Need an MTO Permit?
Your property likely requires MTO approval if:
Property abuts a provincial highway
400-series (401, 404, QEW, etc.) or numbered King's Highways (7, 10, 11, etc.)
Development within controlled distance
Within 45m (800-series) or 90m (400-series) of highway centerline
Creating or changing access
New driveway, widening entrance, or changing entrance use
Work in highway right-of-way
Utilities, structures, or temporary construction activities
Check Before You Build!
Even if your municipality issues a building permit, you still need MTO approval if your property is near a provincial highway. Many builders discover this requirement only after construction has started, resulting in costly stop-work orders. Always confirm with MTO regional office BEFORE applying for municipal building permits.
Common scenarios requiring MTO permits:

- • New driveway to Highway
- • Garage or accessory building
- • Swimming pool (if visible)
- • Property grading changes
Commercial

MTO Permit Application Process (6 Steps)
Determine Jurisdiction & Permit Type
Confirm your property abuts a provincial highway (not municipal road) and identify which MTO permit(s) you need. Check Ontario GeoHub or contact your MTO regional office. Note: Some highways were downloaded to municipalities - confirm current jurisdiction.
Pre-Application Consultation (Highly Recommended)
Contact MTO regional office to discuss your project. MTO staff will advise on requirements, sight line issues, setbacks, access spacing, and potential concerns. This can save months of revisions later.
Prepare Required Documentation
Typical submission requirements vary by permit type:
- Completed application form (available on MTO website for each permit type)
- Site plan showing property boundaries, highway ROW, proposed development, setbacks (to scale, professionally prepared)
- Grading and drainage plan showing how stormwater will be managed (must not drain to highway)
- Building elevations showing views from highway (heights, materials, colors)
- Traffic Impact Study for large developments or new commercial accesses ($5,000-$20,000)
- Sight line analysis for entrances (conducted by Professional Engineer)
- Utility design drawings for encroachment permits (sealed by P.Eng.)
Submit Application & Pay Fees
Submit complete application package to your MTO regional office (email or mail accepted). Incomplete applications will be returned without review.

MTO Technical Review
MTO corridor management staff and engineers review application for compliance with highway safety standards, sight lines, drainage, access management policies, and provincial highway design standards. You may be asked for revisions or additional information.
Review Criteria:
- Sight lines: Adequate stopping sight distance for drivers (critical for entrances)
- Drainage: Stormwater must not drain onto highway or compromise highway drainage
- Access spacing: Minimum distances between entrances (typically 100-250m)
- Safety: No hazards to highway traffic, adequate setbacks from ROW
- Future highway plans: Won't conflict with planned highway expansions or interchanges
Permit Issuance & Conditions
If approved, MTO issues permit with conditions you must follow. Common conditions include construction timing restrictions, required inspections, security deposits, and maintenance obligations. You must obtain this MTO permit BEFORE municipal building permit in most cases.
Important: MTO permit does NOT replace municipal building permit. You need both. Some municipalities require proof of MTO approval before they'll issue building permits. Construction without MTO permit can result in stop-work orders and fines.
Total Typical Timeline: 2-4 months from initial contact to permit issuance (for straightforward applications)
Total Typical Cost: $3,000-$16,000+ (including fees, surveys, engineering, studies)

Common Challenges & Solutions
Challenge: Insufficient sight lines for entrance
MTO refuses entrance permit because drivers can't see far enough along highway to safely enter/exit (e.g., crest of hill, curve).
Solution:
Relocate entrance to area with better sight lines (may require regrading property). Install larger entrance radii for slower turning speeds. Consider shared access with neighboring property. In extreme cases, access may need to be from side road instead of highway. Hire Professional Engineer to conduct formal sight line study to identify feasible locations before purchasing property.
Challenge: Inadequate setback from highway ROW
Proposed building is too close to highway right-of-way, violating MTO setback requirements (typically 14m minimum, up to 45m for 400-series).
Solution:
Redesign building location to comply with setbacks. If property is too narrow, consider variance application (rarely granted by MTO). Review for potential future highway expansion plans that may require additional setback. Consider single-story instead of two-story to reduce visual impact. Always get survey showing exact ROW location BEFORE designing building.
Challenge: Drainage conflicts with highway
Proposed grading drains stormwater toward highway or interferes with highway drainage system.
Solution:
Redesign grading to direct all runoff away from highway. Install on-site stormwater management (detention pond, underground storage). May require pumping system if property drains naturally toward highway. Hire civil engineer to prepare drainage plan showing pre- and post-development flows. Budget $10,000-$50,000 for stormwater infrastructure on challenging sites.
Challenge: MTO permit delayed municipal building permit
Municipality won't issue building permit until MTO approval received, but MTO review is taking 60+ days.
Solution:
Submit MTO application EARLY - ideally 3-4 months before you need to start construction. Run MTO and municipal approvals in parallel where possible. Follow up weekly with MTO corridor management staff on application status. Ensure application is complete when submitted (incomplete = delays). Consider pre-consultation to identify issues before formal submission.
Challenge: Access denied due to highway future widening plans
MTO refuses entrance permit because highway is planned for widening/interchange that will eliminate your access.
Solution:
Request temporary entrance permit until highway work begins (MTO may grant 5-10 year permits). Investigate alternate access from side roads or rear of property. Consider negotiating compensation from MTO if widening will impact property value. Review highway corridor plans BEFORE purchasing property - MTO has 30-year highway plans that show future widenings and interchanges. This is publicly available information that can prevent costly surprises.
