The homeowner life in Canada is changing. We see it everywhere: The once-endless expansion of suburban neighbourhoods has slowed, and highrise cranes now dot the skyline, often even far from city centres. But how much have things really changed? Is the dream of a detached home in the suburbs, with a backyard and a barbecue pit, still attainable? Or is it irrelevant in an age when so many homebuyers are choosing an urban lifestyle instead? Well, it’s probably a good thing young homebuyers are shifting to that lifestyle, because they couldn’t afford a house in the suburbs, anyway. Watch: These Canadian real estate markets are booming thanks to legal weed. Story continues below.

HuffPost Canada built profiles of the typical first-time homebuyer neighbourhood in three Canadian metro areas, using data on housing construction, first-time homebuyer incomes (ages 25 to 34) and house prices ― one profile for 1977, and another for 2017 (the most recent year for which all the necessary data was available). What we found is that in the priciest cities ― Toronto and Vancouver ― millennial first-time buyers today can afford roughly a third as much space as their boomer parents could when they were buying their first homes in the late 1970s.

But while prices have soared, falling interest rates have kept monthly mortgage payments in check. Adjusted for inflation, there’s little difference in buyers’ monthly payments in 2017 and 1977. Between those years, the minimum down payment for an insured mortgage came down to 5 per cent from 10 per cent, also taking some pressure off first-time buyers. But in mid-sized Canadian cities ― as the Halifax example shows ― affordability hasn’t deteriorated to nearly the same extent. In fact, for average-earning first-time buyers, the dream of one’s own front door appears to be alive and well. Here are the sorts of neighbourhoods first-time buyers could afford ― then and now ― in Toronto, Vancouver and Halifax. Boomer Toronto: A 2,070-square-foot house in the suburbs

The 1970s were smack-dab in the middle of the great North American suburban migration, and in 1977, an average-earning household in the 25 to 34 age range could afford a house of up to $340,000 (in 2017 dollars). Since the average selling price for residential properties at that time was $247,000, that meant first-time buyers could afford a typical suburban house, which in the 1970s in the Toronto area averaged around 2,070 square feet in size. Average first-time buyer household income: $73,500 Maximum purchase price: $340,600 Average selling price: $247,000 Maximum monthly payment: $2,500 Maximum mortgage: $318,000 (4.3 times household income) All figures are 2017 dollars.

Between 1977 and 2017, the average income in first-time homebuyer households in the Toronto area rose by 12 per cent, while inflation-adjusted house prices more than tripled, to $794,000 from $247,000. With a maximum purchase price of $505,000 ― about $15,000 short of the average price of a condo ― first-time buyers are limited to smaller condos in the rapidly-growing high-density clusters around the Greater Toronto Area, such as Toronto’s Liberty Village or the central Square One area of Mississauga, Ont. The average size of a new condo in Toronto over the past decade has been 647 square feet. Average first-time buyer household income: $82,500 Maximum purchase price: $505,000 Average selling price: $794,000 Maximum monthly payment: $2,290 Maximum mortgage: $499,000 (6 times household income) All figures are 2017 dollars. Boomer Vancouver: A perfectly average detached house

An average-earning first-time buyer household could afford an average-priced property in 1977, which was $306,000 in 2017 dollars. Like everywhere else on the continent, Vancouver was suburbanizing at the time, and an average house in one of the new suburban subdivisions had 2,180 square feet of living space. Average first-time buyer household income: $79,600 Maximum purchase price: $369,000 Average selling price: $306,000 Maximum monthly payment: $2,667 Maximum mortgage: $342,000 (4.3 times household income) All figures are 2017 dollars. Millennial Vancouver: Still the suburban lifestyle, only smaller

The average income for households in the first-time buyer range fell by 6 per cent in Vancouver from 1977 to 2017, while the average house price more than tripled to $998,000. By 2017, an average first-time buyer household could afford a maximum house price of $500,000, or less than a third of the price of a detached house. Even a majority of condos would be out of range, and only about 8 per cent of listings on the market today would fall within range. Most of those are smallish condos farther out from the centre, in communities like Metrotown of Burnaby, B.C., which is pictured above. So it’s still the suburban lifestyle, only smaller and at a higher altitude. A typical condo built in Vancouver in recent years is just under 800 square feet. Average first-time buyer household income: $75,000 Maximum purchase price: $500,000 Average selling price: $998,000 Maximum monthly payment: $2,262 Maximum mortgage: $494,000 (6.6 times household income) All figures are 2017 dollars. Boomer Halifax: A better-than-average house, wherever you want

For Halifax, we used 1980 numbers, because not all data was available for 1977. Haligonians had lower incomes than Torontonians or Vancouverites back then, but the city’s relatively low house prices meant that if you earned the average for a first-time buyer household, you could afford nearly twice the average house price ($288,000 versus $159,900, in 2017 dollars). At the very least, you could buy something considerably larger than the 1,560-square-foot home that was typical for the area at the time. Average first-time buyer household income: $62,000 Maximum purchase price: $288,000 Average selling price (detached homes): $159,900 Maximum monthly payment: $2,100 Maximum mortgage: $267,000 (4.3 times household income) All figures are 2017 dollars.
