Is Underwood a good place to live?

A good place to live, if you can afford it. Schools do well (A). Health is another plus (A). Prices are high against local incomes (D−). The local economy is weaker than most (D). Overall, that makes a B+, better than 66% of Canadian towns. Its place in the ranking is #295 of 858 in Ontario.

Rents here are the metro area's average, shared by every town and neighbourhood in it. Safety less sure: this is the whole city's figure, because the city doesn't publish open neighbourhood crime rates. Health is graded on the health region's survey figures and life expectancy, with the distance to hospital giving the town its own spread.
