I'll just chime in to say that for our climate, I would avoid the tie coats with no buttons, or coats with just 1-2 buttons. Given the wind chill and snow of Ontario, I find those tie coats do a completely inadequate job since the wind just goes right around the open part no matter how you tie it. Also, they are fiddly, move around when you sit and need to be adjusted every time you get up, need a scarf to fill in the open area at the neck, and often look like bathrobes. I find the same for 1-2 button coats. Great for milder climates - not for ours.
I got a Harris Wharf coat from the Bay at a steal at the end of last season (you may remember) and it is warm, light and will last me for years and years (i wanted a comfortable, warm and not too heavy one I could wear to work.) You might try the Bay at the end of season if you are willing to wait.
Also - you could try a more streamlined puffer that is slightly dressier, that you can layer under. I got this one in caramel at an end of season sale last year and I wear it for EVERYTHING - from early morning walks, to errand, to out to dinner. looks sleek and stylish.
