London Excavation Permits & Site Restoration Bylaws

Utilities and Infrastructure Ontario 3 Minutes Read · published February 12, 2026 Flag of Ontario · By Daniel Roy

In London, Ontario, excavation and site restoration are regulated activities that commonly require municipal permits and coordinated restoration plans. This guide explains when a permit is required, which municipal office enforces rules, typical restoration timelines, and practical steps for applicants and contractors working within London city limits. It translates legal requirements into actionable steps for property owners, utilities and contractors who must comply with city bylaws and engineering standards.

Scope & When a Permit Is Required

Most excavations that affect public property, road allowances, sidewalks, utilities or that require lane closures will need a municipal excavation or road occupancy permit. Private excavations wholly within a private property boundary may still trigger building permits or inspections depending on depth, proximity to services, and soil control measures.

  • Excavation affecting road allowance, boulevard or sidewalk
  • Utility tie-ins, trenching for services, and major grading
  • Any work requiring traffic control, hoarding or sidewalk closure
Always check with the city before breaking ground to avoid work stoppages.

Permit Types & Application Process

London issues permits for road occupancy, excavation and related temporary works. Applications generally require site plans, traffic control plans, and proof of liability insurance. Detailed application requirements and submission instructions are provided by the city permit office[1].

  • Road occupancy and excavation permits: required for works in public right-of-way[1]
  • Traffic control plans and restoration drawings
  • Application fees and damage deposits may be required (see application page)

Applications & Forms

The city publishes application forms for road occupancy and excavation on its permits pages; the exact form names and fee schedules are provided there. If a specific form number or fee is not shown on the public permit page, it is not specified on the cited page[1].

Penalties & Enforcement

Enforcement is led by City of London by-law and engineering staff; inspection and compliance may result from routine inspections or complaints. Specific fine amounts and scales for excavation or improper restoration are not specified on the cited municipal pages and should be confirmed with enforcement staff[2].

  • Monetary fines: not specified on the cited page[2]
  • Escalation: first offence, repeat offences and continuing offences ranges not specified on the cited page[2]
  • Non-monetary sanctions: work orders, mandatory restoration directives, stop-work orders and court actions are used by the city
  • Enforcer and complaints: By-law Enforcement and Engineering/Construction Services (see Help and Support)
Failure to obtain required permits can lead to work stoppage and mandatory restoration orders.

Applications & Forms

For enforcement actions, application for retroactive permits or to dispute orders, contact the issuing department; the city permit pages list submission methods and contact points. If a specific appeal form or deadline is not published on the enforcement page, that detail is not specified on the cited page[2].
