Environmental assessment

On October 18, 2024, the City of Mississauga submitted its final environmental assessment for the 1 Port Street East proposed marina project to the Ministry of the Environment, Conservation and Parks for review and a decision. This assessment examines the proposed lakefill alternatives for additional waterfront parkland and marina services for the site.

We posted an invitation to comment on the environmental assessment on this page on October 18, 2024. Comments were accepted until December 6, 2024.

Based on the comments that were submitted during the environmental assessment review period from Indigenous communities, agencies and members of the public, the City of Mississauga revised its environmental assessment and submitted an amended environmental assessment to the ministry in June 2025 which is posted on the City’s project website.

Notice of completion of ministry review

The ministry has prepared a review of the environmental assessment for Indigenous community, public, agency and stakeholder comment.

The review of the environmental assessment is not the decision about the project. That decision is made by the Minister of the Environment, Conservation and Parks after the comment period is over and the minister has considered all submissions.

The minister’s decision is subject to the approval of the Lieutenant Governor in Council.
