The more I read
the CPC statement, the more weird it becomes. It says "In 2022, Vancouver only managed to approve the construction of 6,269 homes." it obviously doesn't reference a source, and it's completely wrong. The
City's data shows they approved 8,606 homes in 2022. It's possible the report meant to reference Housing Starts, which were around 6,000, but the City of Vancouver, and every other municipality, can't make developers start housing that's been approved.
To require "unaffordable big cities like Vancouver to increase homebuilding by 15% annually or face big financial penalties and have portions of their federal funding withheld" just guarantees slowing development even more, because the city can't make homebuilders build, and withholding federal funding (which isn't much, fortunately) will just reduce homebuilding more, as it's one of the sources of subsidy for non-market housing.
As noted previously, in Metro Vancouver municipalities there are thousands more units approved than are being built, for a variety of reasons, mostly related to the housing market and rising interest rates (both for strata and rental units).
