Amendments to the disclosure statement, and what counts as a material change
Doorvia Guides · July 31, 2026
Developers can change a project, but a material change triggers notice and may give you a right to rescind.
Projects evolve between launch and registration. Ontario's Condominium Act requires the developer to deliver a notice of change when the disclosure statement becomes inaccurate, and where the change is material, the buyer may have a right to rescind within a defined period after receiving notice.
What counts as material is defined by the Act and interpreted narrowly in practice. Losing a proposed amenity, a substantial change to the size or layout of your unit, or a significant change to the property description can qualify; minor design substitutions usually do not.
Send every amendment you receive to your lawyer the day it arrives. The rescission window is short and it does not restart.
