That's simply not true first of all, condos in highly desirable locations continue to sell, perhaps not as quickly as before waiting on interest rates, but they aren't completely stalled like Hamilton's market has. If an LRT station we're adjacent to this development demand would be far greater for units that will benefit directly from that transit connection.
Additionally, this could be shifted to rental, even in just a few of the buildings and the rents would justify the cost of construction if the LRT had an impact on demand.
I'm not trying to downplay the role of interest rates, but what I am saying is that LRT would increase demand, no parking minimums would lower construction cost. The argument I'm making is that interest rates are not 100% of the reason. It could be around 50% of the reason, but the other factors that affect housing construction could be adjusted to reduce stalls like this.
