If I am correct, the 4th edition BB book (that a friend of mine has and I read briefly) has a section on carseats in Canada. I believe there are some incorrect information. For example, the Maxi-Cosi is not available in Canada.

I would be more than happy to help out with your information for the Canadian section. I am going to buy the BB book for another friend who is having a baby. I just wish there are more on the Canadian section though.
