My reccommendation would be Winnipeg Flying Club (St. Andrews, outside Winnipeg) for the single Commercial, on to Perimeter (Winnipeg International) for the Multi IFR.
WFC has their own (pretty good, relatively new) accommodations, by the time they get to Perimeter they should be able to find their way around Winterpeg... several hotels/motels/flophouses around Perimeter give their students discounts, so the last month or so should not be all that expensive.
