On May 27, 2025 Westmount City Council gave preliminary approval to a revised plan for rezoning to allow for high-rises by the Atwater Library. The following day the revised Lemay Plan-Westmount Southeast PPU was posted on the City’s website. Go HERE for the 92-page report.
Below is the height restrictions diagram in the new document (page 54) with the addition of an arrow pointing to the Atwater Library.
As the diagram shows, a 20-storey building would be allowed on the corner lot (former McDonald’s) instead of the 25-storeys called for in the November report. Plus, three more 20-storey buildings to the west on the south side of Ste-Catherine opposite Alexis-Nihon. And a new tower (24 to 29 floors) at Alexis-Nihon.
Our understanding is that the legal effect of the decisions the Council made on Tuesday evening is that only minor changes are possible before the scheduled September vote to finalize rezoning.
The Atwater Library leadership has serious concerns and worries about this revised plan. We have advocated low-rise, human-scale densification, in accordance with the advice of the panel of experts we hosted on May 8, 2025. Four panelists made presentations that are on our YouTube channel.
