To be honest, you need to be more specific with your questions. I'll do my best to answer them. There really isn't one main website that has information for you. For example, if you're looking at schools in Ontario, you may want to look through the OUAC website. For other provinces, look specifically at the law schools websites.
As per cost, it varies, but it would be MUCH cheaper then a US school. The top Canadian schools would run you around 30 grand Can./year. Again, any school website will tell you this information.
hope this helps
