What entry door features suit Mississauga homes best?

We’re planning a front door replacement for our detached house in Mississauga, but we get hit with heavy wind and bitter cold during late autumn and winter. Beyond just looking nice from the driveway, I want to make sure we pick the right functional features like thermal insulation ratings, weatherstripping types, or multi-point locks. For local homes, what specific door features are actually essential for surviving Mississauga weather while keeping energy bills down?
