I'm one of those people who really loves Vancouver and will admit my bias. I actually made a post a few months back talking about my experiences in Vancouver after spending some significant time there and it created quite the discussion and debate (just like now).
Bless you. Admitting our biases makes the conversation much easier. And I think the bulk of that discussion was between you, me and
@dunno haha
I do agree that in some ways Vancouver is "stalling out" in terms of being the poster child of what makes a city lively, livable and exciting. The cost of living coupled with the opioid crisis along with some smaller issues have made Vancouver a great city to visit but not so much to settle down and set up roots.
That is exactly the feeling I get. My own bias aside, which has more to do with very subject factors than anything, over the past couple of years I've felt like the city is becoming less and less of a place I'd consider living, even if the subjective factors (such as weather, politics, the people, etc...) were to my liking. My whole argument is built over the cost-benefit of what the city offers, and the steadily declining socio-economic situation and the ever escalating cost of living put it exactly where you described it: nice to visit, but not for living, because it doesn't not offer enough benefits for what it costs to live there.
If their cost of living was, say, comparable to Calgary's for example (or even a little bit higher), I'd 100% see huge advantages of living in Vancouver over most cities in Canada (I maintain my opinion that Toronto and Montreal are inherently more complete cities, and Montreal is the best bang-for-the-buck in Canada).
I'm very much of the opinion that there are some things we should aspire to and try to replicate that Vancouver has. Density and transportation being the major ones. However, we should be looking at other cities in NA and Europe to get a fair overview of what has and hasn't worked elsewhere. There are always going to be advantages that places like Vancouver and others have that we never will (weather and geography being the major ones) but it's important to also be able to say X city has some problems that we need to avoid.
I honestly believe that we could learn from Vancouver, especially in terms of how they built density in their core, with a really high residential density. If I am not mistaken, almost 1/3 of Vancouver proper's population is west of Main St (some 200k+ people), which is absolutely IMPRESSIVE. That would be the equivalent of having 300k people living in DT/Boyle St/Oliver/Old Strathcona/Garneau/Rossdale, in terms of physical space. Edmonton would be a completely different city if that were to happen.
I think that, considering our climate and geography, our transit would be better off taking inspo from Montreal, like some else suggested.
I do agree with you reasoning on learning from other places around the world, not just in our vicinity. There are a lot of good (and bad) examples of city planning out there. I don't know who said it, but I agree that we need to stop with the "made in Edmonton" solutions for everything, because it's clearly not working.
