Pay rates are lower in Toronto than D/FW. Both metropolitan areas have a similar population. However a recent construction three bedroom, single family home costs about US$1700 per month to rent in D/FW. A similar home is about US$3000 per month in Toronto. Gasoline is US$1.78 per US gallon in D/FW. It's almost US$3 in Toronto. There's no state income tax in D/FW. Why is life in Toronto less prosperous than in Texas?
I don't know enough about D/FW to give you more in the way of comparators, but here's a few:
Toronto is the largest city in Canada and the financial capital of the country - don't compare Toronto's cost of living to Dallas, compare it to New York
Toronto/Ontario is not an oil producing region - Dallas/Texas is - gasoline prices in Alberta, a similar economy to Texas, is much cheaper than in Toronto/Ontario.
Gasoline in Canada in general and in Toronto/Ontario is highly taxed, supposedly to help fun infrastructure in the form of roads, bridges, etc. but we all know that's a liberal lie because liberals hate cars and do everything in their power to fund bicycle infrastructure and public transit. Compare the price of gasoline in Toronto to the price in California where they also have liberal fools who think car owners are evil and must be punished.
Toronto/Ontario has Provincial income taxes because we like to fund things like healthcare which takes up about 50% of every dollar the Provincial government raises in revenue.
Finally, Toronto is growing greatly and one of the most sought after locations for people around the world who want to emigrate to a safe environment. We have on average about 50 to 70 murders a year for a city the size of Chicago. A lot of Asian money has been flooding the housing market here in Toronto. It is a safe place for them to invest and, additionally, investment in this country is one of the criteria for getting considered as suitable for immigration.
None of the above is to disparage or take anything away from Dallas/FW. I know that the recent police shootings there has been bad publicity, but from what I've read and seen Dallas has one of the best and more progressive police forces in your country and has done a great deal to improve police/community relations. We also have some police/community issues but nothing, thankfully, to that extent.
Good luck in Dallas. I'm guessing you're like me, there's no place on earth I'd rather live that right where I live now, Toronto and for you that's probably Dallas.
