Complete Our Thornhill SNAP Action Plan Survey

The City of Vaughan, in Partnership with Toronto and Region Conservation Authority (TRCA), is developing a Sustainable Neighbourhood Action Plan (SNAP) for the Thornhill community.

To ensure the plan is tailored to the needs and interests of residents, we are looking for your feedback: How you would like to be involved, what matters most to you, and what changes and improvements you would like to see in your neighbourhood?

Make sure your voice is heard! Just take a few minutes to fill out the Thornhill SNAP survey.


Toronto and Region Conservation Authority (TRCA) and the City of Vaughan are working closely with neighbourhood community leaders, residents, and businesses to develop a Sustainable Neighbourhood Action Plan (SNAP) for Thornhill.

Retrofits to the natural and built environment will demonstrate implementation of signature strategies that include:

The neighbourhood Action Plan will also support the Region of York Water Efficiency and Climate Action priorities.

About the Thornhill Community

The Study Area boundaries for the SNAP Action Plan are Steeles Avenue to the south, Highway 407 to the north, Bathurst Avenue to the west, and Yonge Street to the east.

The northeast section of the neighbourhood is a Heritage Conservation District, characterized by a wealth of historic buildings, sites, and landscapes dating from the mid 19th century.

The rest of the neighbourhood was mostly built between the 1960s and 1980s. Significant redevelopment is taking place today.

Thornhill also has small commercial areas on its main streets.

The neighbourhood is part of the Don River Watershed, and is home to sensitive target fish species and a healthy urban forest. It is also a Flood Vulnerable Area, at risk of both urban and riverine flooding*.

In addition, Thornhill consumes more energy and water (both indoor and outdoor) than most other neighbourhoods in City of Vaughan and wider York Region.

There are a number of significant capital infrastructure projects planned for this community in the coming years, including flood remediation and stormwater management initiatives, park revitalization and community centre retrofits, and a trail strategy.

There is an opportunity, through SNAP, to leverage some of these projects to achieve higher impact, by adding beauty, ecological function, and recreational opportunities.

*Riverine flooding occurs when the water levels of rivers rise, overflowing their banks. Reducing riverine flood risk is under the mandate of Conservation Authorities like TRCA. Urban flooding consists of street flooding, basement flooding and flooding of other low-lying areas due to the overflow of local drainage systems. Municipalities are responsible for managing this type of flooding.

About the Action Plan

The SNAP Action Plan for Thornhill is currently being developed. It will be a comprehensive plan for neighbourhood revitalization that integrates local community priorities, climate resiliency, and sustainability objectives across the private and public realms.

The Thornhill SNAP will align municipal and partner objectives with resident interests, resulting in innovative urban renewal with measurable impacts on sustainability and resiliency, as well as benefits to community health and well-being.
