This has been working its way in and out of TPB and TEYCC committee meetings forever. Here is a case of a heritage listed building being razed for new development:

" Despite concerted efforts of staff and architects of the new facility, it became clear that patient care could not be integrated on one floor, as needed, if both historic properties were included, said Karapita. The city has approved plans for the site, understanding that the coach house, which is listed as a heritage property, will likely have to be razed.
Staff started toying months ago with trying to save the heritage property by offering it up to a willing taker. Local councillor Kristyn Wong-Tam kickstarted the marketing effort Tuesday with an unusual tweet: https://twitter.com/kristynwongtam/status/450984550512865281"
edit: I posted this here and not in the 571 Jarvis thread because it is relevant to the discussion of the heritage buildings on the M-G site. It provides a blueprint for what M-G could have done - if they had preserved aspects of heritage from the beginning (such as completely retaining one of the buildings) they would have had an easier (although surely still difficult) time getting approvals.
From the staff report for 571 Jarvis & 119 Isabella:
"Given the Residential Program requirements for the Casey House facility, it has been demonstrated that it would be very difficult to retain the Coach House in-situ within without affecting the rest of the project. While city staff have accepted this rationale for demolition, HPS has continued to emphasize that the loss of the coach house could only be supported if the William R. Johnston house ("the Grey Lady") was sensitively integrated into the new facility, including retention of the full building envelope, restoration of the full exterior and selected significant interior spaces and through careful attention to the design of the new building, both in mass and materiality.
The removal of a one storey addition on the east side of the building and the creation of new openings on the east exterior will not have a significant impact on the heritage value of the property."
