Participate early: public input is most effective during the study and comment periods.

What is a public environmental review?

Municipal public environmental reviews—often undertaken as part of Municipal Class Environmental Assessments or project-specific studies—examine potential impacts of public works and private projects that require municipal approval. Reviews typically include a documented study, a notice of study commencement, opportunities for written comments, public information centres or hearings, and a final report or decision. The project lead can be a city department (Planning, Engineering, Transportation) or an applicant working with the city.

How the process usually works

  • Notice of study commencement and opportunities to review study terms.
  • Public information sessions or open houses where study findings are presented.
  • Availability of technical reports, environmental assessments, and impact studies for public review.
  • Submission of written comments, objections, or requests for follow-up to the responsible department.
  • Final decision, record of completion, and any appeal or review steps under applicable provincial or municipal rules.

Penalties & Enforcement

Enforcement of environmental aspects related to municipal projects usually involves multiple offices depending on the matter—By-law Enforcement, Planning Services, Building Services, Engineering, or provincial regulators. Specific fines, escalation schedules, and non-monetary sanctions vary by the controlling instrument. Where the official municipal page or controlling instrument does not list amounts or ranges, this guide notes that figure as not specified on the cited page and is current as of May 2026.

  • Monetary fines: not specified on the cited page for generic municipal environmental reviews; amounts are set in individual bylaws or provincial orders.
  • Escalation for repeat or continuing offences: not specified on the cited page; some bylaws allow daily continuing fines.
  • Non-monetary sanctions: orders to stop work, remediation orders, permit suspensions, or court action may be applied by the enforcing authority.
  • Enforcers: City of Oshawa By-law Enforcement and relevant City departments (Planning, Engineering, Building); provincial ministries may enforce statutory environmental approvals.
  • Inspection and complaint pathways: submit complaints to the City of Oshawa by-law or planning contact page; provincial complaints go to the Ministry of the Environment, Conservation and Parks where applicable.
  • Appeals and reviews: routes depend on the instrument—some decisions are appealable to provincial tribunals or subject to judicial review; specific time limits are not specified on the cited page.
  • Defences and discretion: decision-makers may consider permits, variances, or "reasonable excuse" defences where listed in the governing bylaw or statute; specifics depend on the controlling instrument.
Check the specific project notice or bylaw for any listed fine amounts or deadlines.

Applications & Forms

Many public consultations accept written comments by email or form; some projects publish a dedicated comment form or portal. Where a formal application or permit is required (for example, a grading permit, tree removal permit, or site alteration), the City publishes the form name, number, fee and submission method on the relevant department page. If no form is required for public comment, the official project notice will usually state how to submit comments. Where the City page does not publish a specific form, that absence is noted as not specified on the cited page.

  • Public comment submission: typically by email, online form, or mail to the project contact.
  • Permits that may be relevant: tree removal permits, site alteration permits, heritage approvals—check the specific project page.
  • Fees: vary by permit and are listed on the City fee schedule when applicable; if not listed on the project page, fee is not specified on the cited page.
  • Deadlines for comments: published on notices of study or completion; if no deadline is published on the official notice, it is not specified on the cited page.
When in doubt, submit written comments with a clear request for acknowledgement and a copy of any supporting evidence.
