Great organization there, Stodge. A web site is much better. It may require some work checking all links monthly for changes, though. I'm surprised if this type of information isn't the first thing buyers (who haven't made up their minds on a specific car regardless) look for in these times, because its often the first thing people want to know. And I'm really surprised all the automotive media including Cdn. Driver don't have this maintained up to date, front and centre!
I still go to the following site to get rebate and incentive information (requires free registration, then login to access it), and highly recommend this resource. However you can't take the info as gospel. Sometimes the information doesn't match up with what the manufacturer "says" (which may be the manufacturer not making certain incentives "public"? Don't know!), and sometimes the information isn't available. When it is, it is quite detailed, ie; cash, finance and lease rates by the year, by model:
