	I was just looking online for topographical maps, when I found that the gov hosts them online. Looking at the legend, you can see where they have everything, from tunnels, to waterways, and any other possible landmark you can think off. Below is the link to the site. It is partially zoomed in to Toronto. http://atlas.nrcan...b_50k&hidetextbox= Hope this helps, Will Will

	I have often used this map to find sites. It helped me locate an old ski resort. It sometimes helps to jump back and forth between this map and google earth(if you have high rez in the area your looking at)THe topo map may indicate a building where the satellite view shows nothing. either the topo is wrong or something is hidden in the woods waiting for you to find it. There is also a topo map at the MNR site that covers Ontario only Land Information Ontario I would also suggest checking your local county or city website for topo GIS maps (i have found some for Canadian and American cities and i am sure they have them world-wide) Calvin: It's a magical world, Hobbes, Ol' Buddy . . . let's go exploring!

	Usually the topo is up to date based on the last survey done in the area. These are intermittent. Most of that information can be found in the lower right hand corner of a standard Canadian map, and the files that you'd be getting from NRC's portal should have the info tagged in there somewhere (try reading the image metadata if you can). For our Yankee friends: The USGS also has (or had, at least) freely available maps from their servers, as well. What you really want, though, is a Cadastral and Util map. The stuff that is marked on the Canadian Topographic maps may not be enough to go on. Unsurprisingly, the aerial photos (much better resolution than google images of the earth) cost a little to buy, but you can get them pretty easily. Since NRCan is always updating their maps, it's likely you can find a recent run of them. PEI also has them available for free on their government site. I've never really needed them for Montreal, and I don't know about the more populated parts of Canada, but I'm willing to bet that they're out there using the right search string. Urban development is what happens when the planners are trying to figure out what to do. By the time they have it sorted, the development has already happened.

	http://mapper.acme.com uses USGS topographic maps and aerials, although they are based off of Terraserver-USA, whose server has been a bit spotty as of late. They are both coordinated with Google Map aerials. It would be nice if they could do the same with Ask.com aerials as well. Abandoned
