Are there any online resources for determining building code requirements in Canada?

For example right now I need to know what the proper diameter for a dryer vent to the outside should be. Last week I needed to know how high a flight of stairs can be before hand railings are required . I called the local municipal building inspectors' office to get the answer (24", 60cm). It was successful, but it took 3 attempts to get a hold of someone in the office who could answer. Surely there's an easier more direct way?

This is Canada's National Building Code, but unfortunately they seem only to sell copies of it on CD or printed form.

hmm, looks like there is an online subscription version also. $125 for one year, or $35 for 10 days. A reasonable price if you're in the business but that's pretty steep for a homeowner with only occasional, but strong, need. Thanks. – matt wilkie Sep 14 '10 at 1:08
If I recall correctly, you'll need a provincial code for this information. The national code is more for engineers, and provincial codes are for builders. – Chris Cudmore Aug 28 '12 at 20:58

In BC go to the BC Building Code site. There are a variety of subscription options. The search and index is acceptably good, I have used it extensively.
