Two neighbouring condominium corporations, Ottawa-Carleton Condominium Corporation No. 574 (574) and Ottawa-Carleton Condominium Corporation No. 573 (573), brought cross-applications to determine their legal and financial obligations regarding a shared timber retaining wall requiring replacement. 574 sought a declaration that 573 was responsible for 40% of costs, proportional to the wall's presence on their property. 573 claimed the wall encroached on its property and sought its relocation or a significantly reduced cost contribution (8.11%).

The court dismissed 573's encroachment claim, finding the Site Plan Agreement did not create enforceable obligations between successors in title and that 573 was bound by the original developer's decisions.

The court determined that the wall was a common element benefiting both properties and that 573 was statutorily obligated to contribute to its maintenance.

The court ordered a 60/40 cost split, with 574 paying 60% and 573 paying 40%, based on the proportion of the wall on each property, rejecting 573's arguments for a lower contribution based on hypothetical original plans or perceived benefit.

Substantial indemnity costs were awarded to 574 due to 573's unreasonable refusal of settlement offers and the resulting disproportionately high legal costs.

The Chief Building Official of the City of Cambridge issued an emergency order for the immediate demolition of the designated heritage Preston Springs Hotel due to its unsafe structural condition and persistent trespassing.

The CBO applied to the court to confirm the reasonableness of this order and to recover demolition costs from the owner, Haastown Holdings (Preston) Inc., who consented to both orders.

The Architectural Conservancy of Ontario (ACO) intervened, challenging the reasonableness of the demolition order, arguing that the CBO failed to consider relevant factors (heritage status, appeal to CRB, alternative remediation options) and considered irrelevant factors (cost of remediation).

The court applied a reasonableness standard of review, finding that the CBO's decision was well-informed by expert reports and his own inspections, and that the building posed an immediate danger that necessitated demolition.

The court confirmed the emergency order and the recoverability of demolition costs from the owner, dismissing the ACO's challenge and alternate relief requests as moot or unsupported.
