Looking for Ontario topographic data and property line data; willing to purchase the latter. Shapefiles or file geodatabase files would be optimal. In terms of topographic data, I am looking for: basic outline of Ontario, county or municipal outlines, contour data, water (lines, poly, etc), buildings, and so forth.

    Can you specify further in terms of the data file format, what kind of topographic details you're looking for, software you're using etc? – Joseph Jul 29 '14 at 13:43

You can also look at geogratis, which is a Canadian repository for all sorts of data http://geogratis.gc.ca/geogratis/MostPopular?lang=en this link will guide you to data related to topographic data.

Geobase as a good collection of administrative boundaries, such as Municipalities http://www.geobase.ca/geobase/en/data/admin/index.html

Along with the above mentioned sources, Land Information Ontario data is available, but I can't speak for its accuracy - http://www.ontario.ca/environment-and-energy/land-information-ontario. What you probably want is featured on geogratis.

    I work for a local municipality.... parcels are constantly being re-zoned and split. So I wonder how accurate the parcel lines for any open/free data would be. I know the process is usually updated by MPAC and takes several months - not sure if they do it across the board for Ontario though. – GISKid Jul 29 '14 at 18:20

For a nice set of topographic data for Ontario, there is a fun interactive map which allows you to:

  • Select various areas and zoom in at a high magnification
  • Enable a variety of active layers (such as contour lines, roads, water polygons, conservation areas and so on)
  • Download the selected areas into a number of formats (shp, AutoCAD DWG, DXF etc)

You will have to register with their website if you want to download the data.
