When it comes to the cost of living in Canada, Toronto often takes the spotlight as one of the priciest places to call home. One would be forgiven for thinking that Toronto is the most expensive city in the Greater Toronto Area (GTA), but other cities in the region regularly top the 416 in average cost of living. But now, this Durham Region town necessitates an income of $105,624 annually, with monthly costs totaling $4,401. MississaugaMississauga rounds out the list at $99,816 per year, with monthly living expenses of around $4,159. For a city that owes much of its growth to its proximity to Toronto, the mega-sized suburb has outpaced the cost of living of its neighbour to the east.
