Is there anything similar to DRGs (scanned images of US topo sheets) for Canada?

I need to do metro area maps of Toronto, Calgary, and Edmonton next week and don't have much in the way of source material to trace from.

Not that I'm aware of in the price range we all like - free. I think you'll be scanning paper sources, unless you get lucky on google.

You can download scanned images of 1:50000 sheets for free at the Toporama site. There are unprojected lat/long, so I usually reproject them in Manifold using the 4 corner coordinates.

Or you can buy them on CD (reprojected I think) here:
Patton

The sheets are also available for purchase in vector format at CITS

If you need a grid for registering them, you could try
Mulder's mapsheet manager

Not a DRG, but maybe useful too:

2005 Canadian Road Network - geotorrent.org

It might also be worth looking at the Canadian Cartographic Association's weblog. They've got a couple of postings on Canadian geospatial data resources:

And of course our very own resources section:

Thanks Bryan.

I can't find the part where you download the scanned sheets. There's a link right above the map window to download a GIF of some area, but that appears to be generated from some sort of nationwide geodatabase.

Thanks Bryan.

I can't find the part where you download the scanned sheets.

In the left sidebar, enter NTDB, the mapsheet number then "Display". Once the image is loaded, Click the line above the map which reads "See entire NTDB sheet............". This will load the higher resolution image. Once it's loaded, Right click>Save as
