Winter tires??

I have a 2014 SH-AWD TL A-Spec package. I'm just wondering if I will need winter tires for the upcoming season? I'm in Hamilton and we got hammered pretty good last winter with snow. This is my first winter with the TL. The GM at the Acura dealership where I leased my car told me I wouldn't need them as he has the same car and had no issues last winter. He also said if I really want winter tires and rims, he suggested NOT using steel rims as the lugs won't tighten down properly on the SH-AWD cars? Seems odd to me but he insists not using them to the point the dealership doesn't sell them for the SH-AWD cars and will not install any customers steel wheels either on any SH-AWD.

Sorry for the long story, I'm just a little confused here. Thanks.
