Toronto and Region Conservation Authority (T.R.C.A.)

Description

Since its formation in 1957, the Toronto and Region Conservation Authority (TRCA) has been delivering programs for the management and protection of the watersheds within its jurisdiction.

In April 2008 and March 2014 the Geospatial Centre received vector datasets from the TRCA which cover the municipalities of Toronto, Vaughan, Richmond Hill, Markham, Pickering, Ajax and parts of Uxbridge, Whitchurch-Stouville, Aurora, King, Caledon, Brampton and Mississauga. The fauna and flora layers are very rich in detail. Current data is available from teh TRCA Open Data site.

The datasets provided to the Geospatial Centre include:

Contours (1 metre)
Ecological land classification (distribution and groupings of plant species)
Fauna (significant species: birds, squirrels, frogs: alder flycatcher, bobolink, etc.)
Flora (significant species: woodfern, shagbark hickory, wild ginger, black ash, star-fire, etc.)
Municipality boundaries
Natural cover (forest, meadow, beach bluff, ecological succession, wetland)

TRCA properties
Vegetation community types (sumac cultural, thicket, willow shrub beach, dry-fresh oak-hardwood deciduous forest)
Water courses
Waterbodies
Watershed boundary

Spatial reference and data type

These data sets are available in Universal Transverse Mercator (UTM). zone 17 co-ordinates; horizontal datum is North American Datum (NAD) 83. These data are stored as Esri shapefiles. Other data formats can be accommodated, as the Geospatial Centre has access to a number of conversion utilities.

Data access

To request this data, please fill out the Ask-Us form and include which layers (shapefiles) you are interested in obtaining. The dataset will be shared with you via OneDrive upon completion of the data release agreement form. You may also make an in-person appointment using the same form.
