York Condominium Corporation No. 344 v. Gruss

2026 ONCAT 61 · April 2, 2026 · Notice voided

Why this matters for Alberta owners

TL;DR: This case is the gold-standard precedent on what 'unreasonable enforcement' looks like. A board ordered an owner to remove her dog under a rule giving the board 'sole opinion' discretion to deem any pet a nuisance — and lost. The tribunal stacked up four distinct failures: no independent verification of complaints, no investigation of the owner's defenses, 'moving the goalposts' by shifting the definition of the rule mid-dispute, and acquiescing to a complainant's legal pressure rather than exercising independent judgment. For Alberta owners challenging a fine notice, this case maps cleanly onto the substantial-compliance + prejudice framework: every one of these failures is a defect FineCheck reports should flag.

The most important point this case establishes is that 'sole opinion of the board' language in a corporation's rules does NOT give the board unfettered discretion. The rule here said the board could deem any pet a nuisance "in the sole opinion of the Board". The corporation argued the tribunal should defer to that opinion. The tribunal rejected this — 'sole opinion' still requires the board to act in good faith, with due diligence, within a range of reasonable choices. For Alberta fines: many Alberta condominium bylaws contain similar 'in the board's discretion' or 'in the board's opinion' language. That language is not a shield. The board still has to actually exercise that discretion reasonably.

Four specific failures the tribunal identified, all of which map to FineCheck's analysis:

First, no independent verification of complaints. The corporation here relied entirely on two complainants' subjective views and their videos. The condominium manager admitted under cross-examination that he had no independent evidence the barking was persistent, that he had only been told by others, and that he had never gone to the complainant's unit to hear it himself. For fine notices: a corporation that issues a fine based on a single complainant's say-so, without sending anyone to verify the alleged conduct, has the same defect. Your FineCheck report should flag this if the notice gives no indication of independent observation.

Second, no investigation of the owner's defenses. Ms. Gruss had repeatedly claimed (a) that other dogs in the building also barked and her dog was being singled out, (b) that the primary complainant was actually triggering the barking by standing outside her door to record, and (c) that complaints during specific times couldn't have been her dog because the dog was at her daughter's house. The board never investigated any of these defenses. The tribunal: 'Due diligence means gathering and investigating all relevant information.' For fine notices: if you wrote a substantive response to the warning letter explaining why the conduct didn't happen, who else was involved, or what the actual circumstances were — and the corporation issued the fine notice without addressing any of it — that's an unreasonable enforcement defect.

Third, moving the goalposts. The corporation initially used a '15 consecutive minutes during the day, 5 minutes at night' threshold. When the dog's barking didn't meet that threshold, the corporation issued a letter saying the standard had changed to 'frequency rather than duration' — without notice to the owner, without amending the rule, without an objective basis for the change. The tribunal called this 'moving the goalposts' and found it demonstrated a lack of good faith. For fine notices: if the corporation cited one bylaw provision in earlier warning letters and a different one in the actual fine notice, or applied a different definition of the breach to you than to other owners, that's a goalpost-shift FineCheck should flag.

Fourth, acquiescing to legal pressure. The corporation's decision to file this case was triggered by a separate complainant filing his own tribunal application — and the corporation entered into a settlement where it agreed to commence this case against Ms. Gruss in exchange for that complainant withdrawing his application. The tribunal found the corporation had "simply yielded to the legal pressure applied" rather than making its own reasonable assessment. For fine notices: a corporation that issues a fine because they're being threatened by other owners — rather than from independent assessment of the conduct — is not exercising independent judgment, and that defect goes to the heart of reasonable enforcement.

The bottom line: this is one of the cleanest fact patterns in recent ONCAT decisions on the multi-pronged 'unreasonable enforcement' doctrine. If your FineCheck report identifies any of these defects in your fine notice — no independent verification, no engagement with your written response, inconsistent rule application, or evidence the fine was triggered by external pressure rather than independent assessment — this is the precedent that establishes those defects matter.

What the tribunal said

Selected excerpts from the Ontario CAT's reasoning. Full decision on CanLII.

[20-21] (the foundational deference-only-when-reasonable doctrine) 'It is well established that the Tribunal should show deference to a board's decision regarding enforcement of its governing documents and the Act, when that decision is made reasonably ... What constitutes reasonable enforcement depends on a variety of contextual factors. For example, boards must act in good faith, with due diligence, and the decision must lay within a range of reasonable choices. It must not act capriciously.' [31] (independent verification requirement) 'However, there is no evidence that the corporation has independently verified the complaints it has received. While ... Mr. Laframboise indicated that he has heard Ms. Gruss' dog "from the hallway" he offered no indication of when and/or how often he had heard or noted the barking. During cross-examination, he confirmed that he had no independent evidence that the barking was persistent or continuous, he had only been told by others that this was so. He also confirmed that he had never attended Ms. Burk's unit to hear the barking for himself. ... It appears from the evidence that YCC 344 simply accepted the complaints made by two units as proof of excessive barking and largely accepted their definition of excessive.' [35] (due diligence with conflicting evidence) 'In situations like this, the due diligence of the board becomes especially important. Ms. Gruss, Ms. Burk and Ms. Vercillo each have their own subjective experiences of the situation, likely coloured by the long-term and ongoing animus between them. Thus, it was incumbent upon the corporation to do its own due diligence to determine objectively and in its sole opinion (as per the corporation's rule) whether Chanel's barking is a nuisance in the context of a building that allows dogs. There is no evidence before me that it has done so.' [36] (investigation of defenses requirement) 'Additionally, YCC 344 has not offered any evidence that it tried to independently verify the complaints and/or took seriously or investigated any of Ms. Gruss' objections and/or denials of the complaints. Due diligence means gathering and investigating all relevant information — there is no evidence that YCC 344 carefully considered any of the complaints or alternative evidence provided by Ms. Gruss.' [37] (acquiescence to legal pressure ≠ independent decision) 'The evidence is that, over time, YCC 344 appears to have simply acquiesced to the subjective opinion that the barking is excessive as defined by two unit owners, despite having informed one owner that the barking she was describing would not be considered actionable. It also appears to have simply yielded to the legal pressure applied by Mr. Carney in lieu of making its own reasonable decision about the question of whether the barking rises to the level of nuisance at law in breach of its rule.' [42] (moving-the-goalposts / consistency violation) 'This letter appears to advise Ms. Gruss — for the first time — that the corporation has changed its definition of what constitutes excessive daytime barking. It appears to "move the goal post" so to speak. There is no evidence before me that this shift was related to a change in Chanel's barking (or barking patterns) as verified by the corporation, only that it was suddenly applying different criteria to determine nuisance. What the evidence demonstrates is the YCC 344 defined one standard to Ms. Gruss and then, when the barking did not meet that threshold, it set a new one that captured it. This lends some weight to Ms. Gruss' argument that the board sought to change the way it applied its rule to target Chanel's barking and order her removal. The evidence supports a finding that the corporation has not acted in good faith including being consistent in the application of its rule.'

Connects to FineCheck's framework

• The substantial compliance test

Jurisdictional note: Ontario CATdecisions are not binding on Alberta's CDRT, but the CDRT will look to other Canadian condo tribunals for guidance under analogous statutory provisions until its own case law develops. The substantial-compliance + prejudice framework used in this decision parallels the test in CDRT Policies and Procedures s.7(b).
