Looking for coat: shell front, fleece back
Things like this are out there.  Look at the suppliers of mountaineering clothing as well as cycle manufacturers for innovative use of contrasting fabrics for ventilation.

I have an older model of this jacket:  http://www.patagonia.com/us/product/mens-wind-shield-pullover?p=24991-0-425

It treats me pretty well--wind-proof front, but with fleecy breathable arms and back. 

I believe that, in Canada, MEC carries Patagonia clothing.
