Is it possible to measure the happiness of a city? Point2Homes thinks so.

The online real estate marketplace has released a report which ranks the happiness of Canada's 100 largest cities.

The results may surprise you.

The happiness index is based on 30 metrics including rainfall, commute time, sense of belonging, and median after-tax income.

These metrics fall into four broad categories: Economy and Real Estate, Location and Demographics, Health and Well-being, and Community and Environment.

According to the World Happiness Report, Canada is the 13th happiest country in the world.

But where are the happiest cities in Canada?

According to Point2Home's analysis, they are all in Ontario.
