Aquatic Habitat Toronto

Aquatic Habitat Toronto (AHT) represents a consensus-based partnership between agencies with a vested interest in the improvement of aquatic habitat on the Toronto Waterfront.

Partners include Fisheries and Oceans Canada (DFO), Ministry of Natural Resources and Forestry, and Toronto and Region Conservation Authority (TRCA) in consultation with City of Toronto.

Aquatic Habitat Toronto is responsible for the implementation of the Toronto Waterfront Aquatic Habitat Restoration Strategy (TWAHRS).

 

WHAT WE DO

1. Consultation

Aquatic Habitat Toronto provides support for Waterfront Toronto and other proponents working on the waterfront by facilitating the approvals process.

In order for a project to be implemented on the waterfront, a variety of approvals are required. Examples include environmental assessments (federal and/or provincial) and fisheries approvals. AHT can help you receive the necessary approvals for your project.

When a proponent is working on the waterfront and there is any chance of negatively impacting fish habitat, compensation for the potential loss is required. AHT can help direct and design this aquatic habitat compensation.

AHT invites consultants and project managers to share their project proposals.

2. Research

The other focus of AHT is to evaluate and advance the role of science in the management of aquatic habitat in the Toronto region. The goal is to answer questions about water quality, sediment quality, phytoplankton availability, and a host of other issues.

The answers to these questions can then feed back into the design of future aquatic habitat through adaptive management.

Aquatic Habitat Toronto partners with various universities and government agencies to study the Toronto waterfront:

Research projects include:

ACOUSTIC TAGGING: TRCA has teamed with researchers from DFO and Carleton University on an acoustic fish study designed to gather information about the behaviour and habitat utilization of the fish community inhabiting the Toronto Harbour. The research team has deployed receivers in locations within and around Toronto’s inner harbour. These receivers will communicate with tags surgically implanted in fish, allowing us to track their habitat utilization.

FISH COMMUNITY MONITORING: During the spring, summer and autumn, TRCA monitors the Lake Ontario fish communities within its jurisidiction to determine the composition and abundance of the fishes found by electrofishing. Sampling occurs on an annual basis.

TRCA monitoring staff conduct acoustic telemetry study

 

ABOUT THE TORONTO WATERFRONT AQUATIC HABITAT RESTORATION STRATEGY (TWAHRS)

The goal of the Toronto Waterfront Aquatic Habitat Restoration Strategy is to develop and achieve consensus on an aquatic habitat restoration strategy that will maximize the potential ecological integrity of the Toronto waterfront.

The TWAHRS strategy strives to create a more sustainable waterfront by using an ecosystem approach to increase ecological integrity, to provide suitable conditions for the maintenance of self-sustaining aquatic communities, and to improve ecological connectivity.

The strategy was developed using a consultative, consensus-based approach involving stakeholders and the general public. It emphasizes conservation design based on native and naturalized species, and takes into account human uses of the shoreline and nearshore waters.

TWAHRS contains a wealth of information on the current conditions of the Toronto Waterfront and provides design suggestions for different types of habitat works in different environments.

The strategy is useful for proponents involved in aquatic habitat restoration on the Toronto waterfront.
