The housing accelerator fund only started reaching agreements in September of last year. Though it was campaigned on in 2021 and budgeted in 2022, the fund led to agreements beginning in September of last year.
It's also important to understand that the housing accelerator fund doesn't go toward the cost of building houses; it goes towards incentivizing changes at municipal levels. That will speed up permitting processes and exclusionary zoning. It will increase density around post-secondary institutions, infrastructure, transit and so on.
It will lead to more homes, but the nuance in your question is important. It doesn't actually lead to the construction of specific homes.
