Canadian Winter Jacket

Hi all

Looking for some help with finding a warm winter jacket for Canadian winters.

For reference, temperatures drop to roughly -20C and I need the jacket to be fully waterproof as we also get a lot of rain and/or wet snow. I hike 5-7 days a week regardless to the conditions. I bring my German Shepherd dog with me and although I carry a backpack I like to have large external pockets for poop bags, my phone, treats etc.

Up until now I’ve always gone with ski/snowboard jackets from HH, Northface and mountain warehouse. Mountain warehouse has been great but I find with my use they last me 2 seasons tops.

Thanks for you suggestions!
