hi, i'm also studying for the Canadian DAT.
I've been studying Kaplan and doing the carvings. I also got Topscore Canadian version. It has 3 sample DAT exams, which are helpful. If you need any extra help in any areas, try the IQ publications books. They have Canadian DAT samples for each area. If you order now, you can get them by next week. If not, I think Kaplan is good. One thing I heard though is that the angle discrimination is harder on the DAT than in the Kaplan book. Either way, I've focused on Kaplan as well. The other stuff is for extra practice.
