The Architectural Conservancy of Ontario, Heritage Cambridge (ACO-Cambridge), an unincorporated entity, sought leave to intervene in an application by the Chief Building Official of the City of Cambridge to confirm an Emergency Order for the demolition of the Preston Springs Hotel, a designated heritage property.
The court first addressed ACO-Cambridge's legal status, substituting the parent organization, Architectural Conservancy of Ontario (ACO), as the proper moving party under Rule 26.01.
The court then considered the Rule 13 test for intervention, finding that ACO had a sufficient public interest in the matter, which was deemed to be of public importance.
While granting leave to intervene, the court imposed strict limitations on ACO's participation, restricting its evidence and submissions to the sole issue of the reasonableness of the CBO's Emergency Order and limiting affidavits to two, to prevent undue delay and expansion of the proceeding.
The court also determined ACO to be a public interest litigant but deferred the decision on its liability for costs of the main application to the application judge.
