ATTENTION: There is currently an outbreak of Type C Botulism affecting wildlife along the Toronto Waterfront, including at the Toronto Islands and Tommy Thompson Park. This is a naturally occurring toxin that has accumulated in the environment because of the recent hot weather, and it is expected to decrease as temperatures drop over the next few weeks. Type C Botulism does not pose a risk to humans, however, there could be potential implications if you consume infected fish. Please be aware of this outbreak. We advise to avoid consumption of fish caught at Tommy Thompson Park and the Toronto Islands until the outbreak clears.

NOTICE: Tommy Thompson Park Entrance Revitalization Project

The Tommy Thompson Park Entrance Revitalization Project is entering phase two: parking lot construction. This phase of the project will improve surface drainage and stormwater handling through grading and installation of vegetated swales, and will formalize drive aisles and parking stalls to maximize vehicle capacity, addressing the existing informal nature of the parking lot. Construction is scheduled to start September 16, 2021 and is expected to be complete by November 15, 2021. The parking lot will be closed for the duration of construction. Parallel parking is available on Leslie Street, as signed.

Phase two follows completion of phase one in May 2021 which included construction of the pavilion, visitor arrival and assembly areas, and park access trails. Overall, this project aims to improve visitor experience at the entrance to Tommy Thompson Park. The pavilion building includes highly anticipated public washrooms, a water bottle filling station, bike racks, outdoor gathering spaces, and storage for park programs. This small building is complemented by separated pedestrian and bicycle access paths, a raised pedestrian area, and a formalized parking lot with vehicle access off Unwin Avenue.

Trails remain open for social distanced passive use. Be aware all maintenance operations have been suspended, and visitors use the trails at their own risk. Note that the parking lot is open. Parking is not permitted on Outer Harbour Marina Road.

The Tommy Thompson Park NATURE CENTRE and BIRD RESEARCH STATION are CLOSED. Toronto and Region Conservation Authority (TRCA) has closed these facilities to protect visitors, staff and all other attendants, from the potential risk of contracting COVID-19.

TRCA and the City of Toronto enforce park rules to ensure the health and safety of visitors and wildlife at Tommy Thompson Park. Unfortunately, the rise of violations at the park has led to the increase of enforcement from both organizations, to educate visitors and turn away those looking to enter the park with pets. We are also working to engage the Toronto Police Service, as our mutual enforcement officers cannot be on site 24-7, and we understand that additional patrols are required after hours to address infractions that are occurring. TRCA has resumed the TTP weekend programming. Unfortunately, due to the pandemic the Nature Centre will remain closed, however staff will conduct park patrols to educate visitors as well as log and report infractions. All parties are committed to protecting the park and we will adapt our efforts accordingly, based on the behaviours of the visitors to the site. If you visit the park and would like to report an infraction, please contact 311 or for more information contact
