Okay - I have to add my two cents worth. I drink beer, my drink of choice, and I also have been to 2 beer schools. Molson Canadian, no offense, is referred to by all the beer teachers I have met, as the "pee" of beer. It is cheap to make and really gross. Once you taste beer with longer manufacturing time, you really begin to understand that run of the mill beer just isn't that great.
So, in my honest opinion, I would get him microbrewery beer, or perhaps, something like Sleeman's honey brown, or Alexander Keith's is nice as well. If you get them something like Canadian, Coors light, or Blue, it would be just like drinking Bud, and that's not a change for them.
Just my thoughts,
Jo
