I fail to see why this Bill 23, Schedule 6 has anything to do with building houses faster at a rate of 150,000 per year. Since the Heritage Act was invented how many designations have been granted?
According to Provincial Power under Par. IV of the Ontario Heritage Act, updated Oct 25, 2022, but published March 26, 2022, the number of designations by Municipalities is:
Individual Properties 7200
Conservation Districts 130 (containing more than 24000 properties)
It is not clear the time period over which these 7330 properties were protected. In any event, the rate of new designated properties will be much less than 7000/ year and probably declining if a good job on heritage protection has been enacted in the past.
The above demonstrates that the Ontario Heritage Acts have no impact on building houses faster. And according to the stated

Regulatory Impact Assessment
If passed, the changes resulting from Schedule 6 of the More Homes Built Faster Act, 2022 and accompanying proposed regulatory changes would primarily impact municipalities, with some impacts to ministries and prescribed public bodies.

"Work is currently underway to analyze possible administrative and other compliance costs to municipalities and other impacted stakeholders that may result from this proposal. To inform this analysis, we encourage you to provide your feedback".

This Schedule 6 should not be part of Bill 23. The Ontario Conservative part of Government rammed through Bill23 without speaking to and showing some concern on well articulated amendments from the Opposition at Committee Level.
