Environmental assessment act 
Section 17.15 
Notice of approval to proceed with a part II.3 project

RE: 1 Port Street East Proposed Marina Project

Proponent: City of Mississauga

EA File No.: EA 03 10 - 19071

Part II.3 (Comprehensive Environmental Assessments) of the Environmental Assessment Act establishes the requirements and authority for preparing, submitting and deciding an application for approval to proceed with a Part II.3 project under the Act.

Pursuant to the transition provisions in Ontario Regulation 53/24 (Transition and General Matters) under the Environmental Assessment Act, the proposed 1 Port Street East Proposed Marina Project (“Project”) is deemed to be a Part II.3 project. This is because, before February 22, 2024, the Proponent had given a terms of reference in respect of the Project to the ministry under the former subsection 6(1) of Act and no decision had been made under the former section 9 of the Act in respect of an application for approval to proceed with the Project.

An application consists of a terms of reference and an environmental assessment. In respect of the Project, the terms of reference was approved by the Minister on September 16, 2021. The Proponent submitted its Environmental Assessment to the ministry on October 18, 2024.

A seven-week comment period followed the submission of the Environmental Assessment to the ministry, during which time any person could submit comments about the Environmental Assessment and the Project. The Proponent submitted an amended Environmental Assessment on June 17, 2025.

The ministry review of the Environmental Assessment was completed on November 16, 2025, and notice was provided in accordance with the Act. The ministry review concluded that the Environmental Assessment was prepared in accordance with the approved terms of reference and the Act and contained sufficient information to assess the potential environmental effects of the Project. There were no outstanding issues from the Environmental Assessment process. The public, government agencies and potentially impacted Indigenous communities had an opportunity to comment on the Environmental Assessment, the Project, and the ministry review during the five-week comment period.

The Proponent and the ministry provided potentially impacted Indigenous communities with opportunities for consultation with respect to the terms of reference, the Environmental Assessment, and the ministry review.

All comments submitted during the statutory comment period have been considered. No requests for a hearing by the Ontario Land Tribunal were submitted. I am not aware of any outstanding issues with respect to the application which suggest that a hearing should otherwise be required.

Having considered the purpose of the Act, the approved terms of reference, the Environmental Assessment, the ministry review of the Environmental Assessment and submissions received, I am giving approval to proceed with the Project, subject to the conditions set out below.

Reasons

My reasons for giving approval are:

  1. The Proponent has complied with the requirements under the Act.
  2. The Environmental Assessment has been prepared in accordance with the approved terms of reference.
  3. Taking into consideration the Proponent’s Environmental Assessment and the ministry review, the Proponent’s conclusion that, on balance, the advantages of this Project outweigh its disadvantages appears to be valid.
  4. The Proponent has demonstrated that the environmental effects of the Project can be appropriately avoided, managed or mitigated.
  5. Given the Proponent’s Environmental Assessment, the ministry review and the conditions in this Notice of Approval, the approval of the Project would be consistent with the purpose of the Act.
  6. There are no outstanding concerns raised by government agencies, the public, or potentially impacted Indigenous communities that cannot be addressed through commitments in the Environmental Assessment, through the conditions set out below or through future approvals that will be required.
