Process for submitting an Excavation By-Law Infraction

  1. Complete and submit our Excavation By-Law Compliance Form
  2. Once a form is submitted, an inspector will make a site visit to determine if it is a valid infraction.
  3. Once this has been established, a letter is sent advising the specifics of the infraction and what is required for compliance of the by-law, including how long the resident has to complete the modifications for compliance.

In addition, anyone who is in violation of the City's by-law and does not comply with a notice that is issued by the City by-law enforcement office may be subject to legal action.
