I have been running in winter for a long time and have gear that has lasted.
You will pay a little more at first but it lasts.
I have running pants from Sporthill, I think MEC carries it.
I also have North Face Running tights for warmer winter weather.
I use a Sporthill zip up turtle neck and a sporthill running vest.
For the first layer I use Nike fleece long sleeve shirt over a Nike long sleeve dri fit.
I also have Nike dri fit short or short cut New Balance shorts for under the pants.
Get a pair of good gloves, neck warmer, and toque. These do not have to be fancy or pricey. ( maybe Lululemon has them

)
I also run with Nike Air structure triax that are selling for around $93.95 us on zappos.com, in Calgary they are over $125.00.
Good luck with the winter running.
