For a Saskatoon homeowner, the more useful question is what SaskPower and SaskEnergy have filed for locally, since those are the two bills that actually show up in a household budget here, not a rate change filed for a utility outside the province.
Rising utility costs do factor into CMHC's mortgage qualifying guidelines, which weigh housing costs at roughly 39 percent of gross income and total debt at 44 percent, so a real increase in either bill can affect what a household can carry going forward.
For a homeowner weighing whether rising costs are a reason to downsize now rather than later, that math is worth running properly. Get your hand-reviewed valuation from Joel Dyck.
