A few news items regarding the A-Class (in Canada) that have come out in the last couple of days!
First, it was announced that Canada will get the A35 AMG. Most likely it will arrive as a 2020 model.
Also, Mercedes Canada has stated that with the sedan and hatchback, both will be available with 4Matic. This article also states that the 4Matic sedan with the Premium Package is intended to come in under $40,000 CAD.
Edit: also reading the second article, the sedan will have the 188 hp 2.0L (A200?). I know that the hatch is supposed to be the A250 model with the 221 hp 2.0L.
