The new immigration levels plan will cause a 0.2 per cent population decline over the next two years, a government press release said. It said the plan will also “reduce the housing supply gap by approximately 670,000 units” over the next few years.

We have 41m people. A 0.2% decline is around 82,577 people. So the 670,000 fewer units isn’t relative to the current supply, it’s relative to what the demand would have been.
