you need to do the math before you make conclusions like that. property taxes aren’t based on just the value of the property, it’s the value of the property times the mil rate.
assuming the average house prices and the mil rates quoted are accurate, the edmonton owner would pay 0.944475 percent of $420,507 or $3,972 per year in property taxes.
the calgary owner would pay 0.065718 percent of $557,000 or $3,660 per year.
even though his house is worth 25% less, the edmonton owner will pay 8.5% more in property taxes than the calgary owner.
