Peter Spear, a local Vancouver PG pilot, has designed a software program that incorporates all the Canadian airspace in a graphical interface, which is much easier to deal with vs. a paper map to figure out where the boundaries are.
The website is here: http://www3.telus.net/cschwab/viewer/check_airspace.html
You can zoom in and hover to see where the various airspaces are, and can switch from map to satellite view. If you hover over Mt. Washington you'll get class D. And if you double click you'll get additional info (eg. if transponders required etc). You can also upload igc files to see if pilots busted any airspace...
We've found Peter's program to be very accurate as it uses data directly from the Designated Airspace Handbook.
