I live in eastern Canada, I've had my Venue since early February 2021. Unfortunately (or fortunately) I haven't experienced any significant snowfall since I got the vehicle (only light snow which was fine) so I can't tell you first hand how it handles in 'deep' snow but the performance will have a LOT to do with the type of tires (I recommend something with good winter driving reviews like Michelin X-Ice).
Having said that......the Venue is a small vehicle with front wheel drive, and only a 1.2 liter engine....it is NOT the best choice for a winter vehicle. Is it a terrible choice? That remains to be seen. As far as your question about hills, it will go up hills just fine at normal city speeds without having to hold the pedal down but if you want to go at highway speeds or if you want to pass someone, you will probably have to floor it. If you are looking for a vehicle with adequate highway/hill power that handles well in the snow there are a LOT better options than the Venue. Remember, the Venue uses the same platform as the Hyundai Accent which is a tiny sub-compact car that wasn't necessarily highly regarded for performance.
