Whitby, Ontario requires an Environmental Impact Assessment (EIA) or comparable study for many development proposals that affect natural heritage, waterfronts, wetlands or significant vegetation communities. This guide explains when an EIA is typically requested, who reviews it, how to prepare and submit the study as part of a development or site-alteration application, and where to find official forms and contacts. It summarizes statutory reviewers, typical review steps and practical action items to help applicants avoid delays during planning approvals.

When an EIA is required

Whitby’s Official Plan sets environmental policies that trigger an EIA or Environmental Impact Study as part of development and site-alteration applications; applicants should confirm requirements with Planning staff before preparing technical reports Whitby Official Plan - Environmental Policies[2].

Confirm EIA triggers with the planning intake officer before commissioning consultants.

Preparing and submitting an EIA

Typical steps include a pre-consultation meeting with Town planning, a scoped Terms of Reference for the study, field assessment by qualified ecological professionals, and submission as part of the development application package. Submitters must also consult the local conservation authority for permit or watershed-specific guidance.

  • Arrange a pre-consultation with Whitby Planning and Development: Town planning & development information[1].
  • Prepare a Terms of Reference that defines scope, methods, and timing for fieldwork.
  • Field assessments should document species, habitat features, buffers and proposed mitigation.
  • Include maps, GIS data, photo documentation and a mitigation monitoring plan.
  • Where required, coordinate with the conservation authority for permit needs and aquatic/shoreline matters.

Review process & timelines

After submission the Town reviews the EIA alongside planning applications; peer review by third-party ecological consultants is common and may be required at the applicant’s expense. Timelines vary by project complexity; discuss timeframe at pre-consultation.

Peer review fees and timelines are set on a project-by-project basis and are confirmed at intake.
