Studies have concluded that people, fish and wildlife may experience negative health effects (risks) if exposed to the contaminated sediment in KIH. Despite several decades of time for natural recovery, several areas have not recovered enough to be safe for current uses.

Most recreational activities in and around the harbour, like boating, kayaking, rowing, and hiking, are safe if skin contact with sediment is minimized or avoided. People should avoid touching the sediments and eating anything that may have touched the sediments. If sediment does contact your skin, simply rinse it off with site water or a shower, and wash your hands before eating. Consumption of fish from the inner harbour is currently restricted. Information of fish consumption advisories in Ontario can be found using the Eating Ontario Fish guide (https://www.ontario.ca/page/eating-ontario-fish-2017-18).

Removal of the contaminated sediment is the best way to permanently reduce the health risks. The need for removing chemicals will be balanced with respect for the environment, especially areas of sensitive or valued habitats. For example, the sediment will be removed when fish are not spawning and turtles not moving across the work area. Sensitive habitats will be identified and considered carefully in the development of the sediment management plan and impact assessment.

The project team will be looking for opportunities for habitat conservation gains that will improve existing habitat and address present ecological impairments. Shoreline plantings and other natural options for shoreline areas will be considered as part of detailed design.
