Toronto winters on average seem to last 6 months while for Montreal it is 7 months. Also, Montreal gets more snow than Toronto on average. Montreal's average snowfall for a winter season is 85 inches and for Toronto it is 52 inches so on average Montreal gets almost 3 feet more snow than Toronto every winter season. Montreal seems to be at its best in summer, late spring, and early fall. I just don't see how it would be nearly as great in winter.
For a broken window (or leaking seal in multi-pane unit), for a standard roughly 2x3 foot window, can run from low of about $75-125 for single pane to more like $200-300 range for triple pane, depending on construction and any special ultraviolet or heat reflective coatings.
Cost Factors. Replacing a window costs an average of $300 to $700 per window. This assumes that the replacement window is going into an existing and structurally sound frame on a ground floor. Replacing windows in a typical three-bedroom, single-story home with ten windows can cost from $3,000 to $7,000. This cost can easily double for a two-story home. In the case that a window frame must be replaced, it is called a new construction window. A new construction window can increase the cost of replacement by as much as 50% to 100%, raising the average cost to anywhere from $5,000 to $40,000.
