The applicants appealed the City of Ottawa's refusal to repeal a heritage designation by-law for their property.
The property had been designated based on a single criterion for cultural heritage value or interest (CHVI) under the previous regulations.
The applicants argued that recent amendments to O. Reg. 9/06, which now require two or more CHVI criteria for designation, invalidated the by-law.
The Tribunal found that the amending by-law remained valid under the transition rules of the regulation.
However, evaluating the repeal application on its merits under the new regulation, the Tribunal concluded that the property's limited heritage contribution did not warrant continued designation.
The appeal was allowed and the designation by-law was repealed.
