Essentially, Edmontonians are becoming poorer than the rest of the country.
This makes absolutely no sense, from a financial perspective. For as long as our income (and disposable income) remains higher, which it has, you can always invest the surplus income in high return portfolios and actually get more appreciation than you'd have with real estate. It also frees up income to purchase multiple properties and have additional income streams, etc... It's much more a matter of financial education and risk aversion.
Expecting to build equity with such returns as those of the GTA or Lower Mainland is simply the laziest way to do it.
Not to say that it wouldn't be healthy for the development market in general, especially the condo market, if prices had a slightly more aggressive uptick, but frankly, unless wages rise as fast as real estate prices, I definitely don't think we want to see things like we saw in Toronto or Vancouver, where starter 600sqft condos cost $500k+, and if you ever want to have a family and live in a decently spacious place, you'd better hope that you are in a dual-income family with both making upwards of $100k/year to even begin dreaming about anything other than renting.
There has to be a balance between a healthy market and affordability, otherwise, what we'll see is a lucky few who will be able tu buy during this low period, make A LOT of money on these properties, and be left with generations of young people who cannot even dream about owning a home until they're closer to retirement than to their youth.
Also, I'll be the first one to say: if Edmonton gets nearly as expensive as Toronto or Vancouver I'll be the first one to jump on a plane a move to the GTA. As much as I love Edmonton, there's ABSOLUTELY NOTHING that would make me chose Edmonton over Toronto in a condition of similar housing prices. Out of our major English speaking cities (sadly, I'm as likely to be able to build a career in Montreal as I am to do it in Moscow), the only one that comes relatively close to justifying the high housing prices is Toronto (by far the most complete metropolis of the country).
Honestly, at this stage, looking at housing prices, Edmonton (because it's affordable, especially considering wages and what the city offers) and Toronto (because it's a proper global metropolis) are the only two major cities I'd live in by choice. None of the others is worth what they cost, IMHO. Vancouver is overrated and neither Calgary or Ottawa offer much more to justify the price gap between them and Edmonton. If I was ever able to establish myself in Montreal, it would likely be my top choice, for lifestyle and affordability (almost as good as Toronto, just as affordable, if not more, than Calgary).
Note the that I don't consider Halifax, Winnipeg, Saskatoon, Regina, Victoria or QC City as being nearly on the same tier as Calgary, Ottawa and Edmonton, and Montreal, Vancouver and Toronto are also in a different tier.
