At this point I think 80% of the practical fixable municipal planning level troubles in Vancouver boil down fairly simply to the municipalities not permitting enough density in the right areas. We could argue about transportation infrastructure and greenfield development too but those are not easy for the municipalities to change.
Here's a story about Port Moody fighting against densification around the SkyTrain line there with pictures of the low-slung buildings and parking lots that the billion-plus dollar line runs through:

It talks about how the City of Vancouver had to be pulled into an agreement to allow density along the Broadway corridor too. Commercial Drive station is still low density with a Safeway and parking lot next door. That's one of the major transfer points here, one of the best places to live if you rely on transit, and it handles millions of passengers a year.
IMO the province should start talking about whether this town of 30,000 should be merged with Coquitlam. That can be the backdrop for the Port Moody politicians discussing how much they want to obstruct development.
