Ontario’s Ecological Survey Windows

The timing for in-water work periods are set by the Ministry of Natural Resources and Forestry (MNRF) and are variable depending on project location and the fish species present. Before starting in-water work, it is advisable to submit a Request for Project Review (RFR) to Fisheries and Oceans Canada (DFO).

For more guidance on determining the specific timing windows for your site, or for assistance with a RFR, feel free to reach out to us at Blue Heron Environmental.
