Baby wearing during winter

Just wondering what people’s thoughts/advice on baby wearing during the cold winter months.

Do I dress my daughter in her snowsuit and then put her in carrier? I have read your not supposed to do that?

Or is it important to buy a winter carrier cover to put over her? I live in Canada and when we get big dumps of snow bringing a stroller outside Isnt an option... I also want to be sure she’s nice and warm.
