Transportation Ontario 4 Minutes Read · published May 26, 2026 Flag of Ontario · By Daniel Roy

St. Catharines, Ontario contractors must follow municipal rules for any work that occupies or alters the curb, boulevard or public right-of-way. This guide explains when a curb-use, encroachment or road-occupancy permit is typically required, who enforces the rules, how to apply, and practical on-site steps to stay compliant before starting construction or site works.

Always confirm permit requirements with the City before any curb or boulevard work begins.

When a Curb Use or Development Permit Is Required

Common triggers for a permit include new or widened driveways, temporary construction access, placement of materials on the boulevard, excavation within the road allowance, or any permanent encroachment such as retaining walls or steps that sit on city land.

  • Driveway cuts, new aprons or curb replacements.
  • Temporary construction access, hoarding, or scaffoldings that affect the curb or lane.
  • Permanent encroachments on the boulevard (fences, steps, planting beds).
  • Work requiring closure or traffic control on city roads.

Penalties & Enforcement

Enforcement is administered by municipal departments including By-law Enforcement, Public Works/Engineering and Building Services. Specific monetary fines, escalation rules and the text of applicable by-laws are not always listed on a single consolidated page; where amounts or sections are not shown on the cited City pages the entry below notes that fact and points to official contacts for complaints and inspections.[2]
