Executive Summary: Key Legal and Evidentiary Issues

• Dispute focused on whether Konzelmann’s outdoor hospitality events at its winery contravened the Town’s agricultural zoning by-law and a site-specific site plan agreement.
• Evidence from neighbouring winery Brox described interference with normal farming operations and nuisance from amplified music, traffic, and event activity near shared property boundaries.
• The Town’s historic practice of issuing “special event permits” and its later decision not to enforce the zoning and site plan directly against Konzelmann raised questions about municipal enforcement discretion.
• The court analyzed whether mandamus could compel the Town to enforce its by-laws and whether s. 440 of the Municipal Act allowed injunctive relief against a municipality, not just against private contraveners.
• Konzelmann ultimately admitted that its 2024–2025 outdoor events breached both the zoning by-law and its site plan, consenting to permanent injunctions regulating future land use.
• The court found no enforceable duty on the Town to prosecute zoning breaches, dismissed the application against the Town, and left any monetary costs to be determined later, if at all.

Background and parties

Brox Company Limited and Konzelmann Vineyards Inc. are neighbouring wineries in Niagara-on-the-Lake, Ontario. Both properties are zoned “agricultural” under the Town’s comprehensive zoning by-law. Within this zone, the primary permitted use is farming, while farm wineries and larger estate wineries are allowed as secondary uses. Operation as an estate winery requires a site-specific zoning amendment and an associated site plan agreement that precisely defines permissible winery-related activities on the land. Konzelmann obtained such a site-specific amendment in 1987 and, in 1994, the Town approved an expanded by-law and site plan allowing indoor hospitality uses, the retail sale of wine, and an agricultural market. The Konzelmann-specific instrument was last updated in 2009. Crucially, it did not authorize outdoor hospitality events such as weddings or large gatherings. Despite this, beginning around 2017, Konzelmann hosted outdoor special events near a lakeside gazebo close to Brox’s residence, agricultural buildings, and vines. These events were initially supported through the Town’s “special event permit” policy, under which Konzelmann obtained single permits covering multiple events across a season. In 2023, for example, a single permit covered 21 separate outdoor events between May and October.

Neighbouring land use conflict and alleged nuisance

Brox’s president, Edward Werner, attested that the outdoor events significantly affected Brox’s farming operations and enjoyment of its land. The events, often involving amplified music and a concentration of guests and vehicles near the shared boundary, were said to restrict the safe application of pesticides and interfere with ordinary agricultural tasks for fear of disturbing guests. Vehicles were sometimes parked outside designated areas, causing additional disruption. Werner also linked the ongoing event activity to the collapse of a potential sale of the Brox property, asserting that prospective purchasers were deterred by the continuing nuisance and uncertainty over lawful land use next door. Brox framed the core problem as an improper commercial or event-driven use being introduced into an area zoned for agriculture, undermining both the intended planning framework and Brox’s ability to operate as a farm winery.

Dealings with the Town and evolving enforcement stance

Werner met with Town officials multiple times in 2023 and 2024 to complain about Konzelmann’s outdoor events and to urge enforcement of both the general zoning by-law and Konzelmann’s site-specific agreement. For several years, however, the Town had facilitated the events through its special event permit regime rather than zoning enforcement. According to evidence from Kirsten McCauley, the Town’s Director of Community and Development Services, the Town’s stance began to shift in the fall of 2023. At that time, Town staff met with Konzelmann, advised that the frequency and scale of the outdoor events required a zoning amendment and revision to the site plan agreement, and indicated that going forward the Town would no longer issue a single special event permit to cover multiple outdoor events. In spring 2024, Konzelmann nonetheless submitted an application seeking one special event permit for 17 outdoor events between June and October 2024. That application was never circulated internally for processing and no permit was issued. Despite the absence of a permit, at least eight outdoor events took place in 2024 by the time Werner swore his affidavit, and further evidence revealed that outdoor events continued into 2025.

Konzelmann’s evidence on municipal communications

Konzelmann’s president, Jim Reschke, accepted that the written site-specific agreement did not authorize outdoor special events. He explained that from 2017 to 2023 Konzelmann had operated its outdoor events through the Town’s annual special event permit process. He recalled a meeting with the Town in the fall of 2023 but did not remember being clearly told that rezoning or a site plan amendment would be required or that the practice of issuing a single multi-event permit was ending. Reschke testified that, in relation to the 2024 season, he was told by someone at or for the Town, possibly its counsel, that the Town “can’t issue a permit, but we’re not going to stop you from doing events” and that the Town had allowed such events in the past. On that understanding, Konzelmann went ahead with the 2024 events despite not having a valid special event permit and without updating the underlying zoning or site plan agreement.

Relief sought and initial procedural outcome

In 2024, Brox commenced an application seeking relief against both Konzelmann and the Town of Niagara-on-the-Lake. Against Konzelmann, Brox sought declarations that outdoor events on the Konzelmann lands were contrary to the Town’s zoning by-law and inconsistent with the approved site plan agreement, together with a permanent injunction restraining any land use not permitted by the by-law, inconsistent with the site plan, or non-compliant with any licence issued by the Alcohol and Gaming Commission of Ontario. Against the Town, Brox sought injunctive relief preventing the Town from permitting Konzelmann to use its lands in ways that breached the zoning and site plan regime and, in substance, orders in the nature of mandamus compelling the Town to enforce its zoning by-law and site plan. Brox also invoked s. 440 of the Municipal Act, 2001, which allows a taxpayer or municipality to seek a statutory injunction to restrain contraventions of municipal by-laws. When the application came on for hearing, Konzelmann chose not to contest Brox’s zoning position. Instead, it consented to the requested declarations that its 2024 and 2025 outdoor special events at the subject lands were in contravention of both the Town’s zoning by-law and the Konzelmann site plan agreement, and it accepted a permanent injunction strictly limiting its future use of the property to uses authorized by those instruments and by any applicable liquor licence conditions. A formal order reflecting these admissions and the injunctive relief was issued as Schedule A to the judgment; it expressly preserved the court’s jurisdiction to decide the remaining dispute between Brox and the Town.

Legal framework on mandamus and statutory injunctions

With Konzelmann’s position resolved by consent, the live issue became whether the court should compel or restrain the Town itself. Brox argued that the Town had knowingly allowed clear breaches of its zoning by-law and site plan agreement to continue unchecked, and that the court should order the Town to enforce its by-laws and to refrain from encouraging or facilitating any further contraventions. In support, Brox sought relief in the nature of mandamus—an extraordinary remedy that can compel a public body to carry out a legal duty—and also relied on s. 440 of the Municipal Act, which allows a taxpayer to seek a court order restraining the contravention of a municipal by-law. The Town accepted that its zoning by-law and Konzelmann’s site-specific agreement did not authorize outdoor special events, but it argued that decisions about investigation and enforcement are matters of broad municipal discretion. Because the zoning by-law did not impose any specific obligation on the Town to prosecute offences or take particular enforcement steps, the Town said there was no “clear legal duty” capable of being enforced by mandamus. The court agreed. Reviewing prior authorities, the judge emphasized that mandamus is only available where a public authority has a legal duty to act, not merely a power or discretion. In cases such as Freitag v. Penetanguishene and Hanzelka v. Oshawa, courts had held that where a by-law does not require enforcement action, mandamus cannot be used to force a municipality to enforce it. Here, the zoning by-law imposed no positive enforcement duty on the Town, so relief in the form of mandamus or prohibition was unavailable. The court also examined s. 440 of the Municipal Act, which codifies a statutory injunction remedy allowing either a municipality or a taxpayer to seek a court order restraining contraventions of municipal by-laws. Case law interpreting this provision confirms that it was designed to give both municipalities and taxpayers a direct tool to stop unlawful uses, without having to rely solely on prosecutions or municipal enforcement discretion. The judge noted that taxpayers have successfully used s. 440 to restrain other private landowners in breach of by-laws, but Brox identified no authority where that section had been used to obtain an injunction directly against a municipality.

Assessment of the Town’s conduct and the public interest

The court accepted that there is a strong public interest in the enforcement of zoning and other public welfare by-laws, and that when municipalities themselves seek statutory injunctions under s. 440 they are presumed to be acting in the public interest. That presumption often allows them to obtain injunctive relief without detailed proof of irreparable harm or a balancing of convenience, since an ongoing breach of law is treated as inherently injurious to the public interest. However, the judge observed that municipal enforcement discretion, while broad, is not unlimited; municipalities must act reasonably and in good faith and can be denied relief where their conduct is arbitrary or reflects bad faith. In this case, the Town did not dispute Reschke’s evidence that Town representatives had said they would not prevent Konzelmann from continuing to hold events even after permits ceased to be issued. The judge treated that stance as an exercise of enforcement discretion. On the particular record, though, there was no allegation that the Town had acted arbitrarily or in bad faith, and no evidence that it had selectively enforced by-laws against some landowners but not others. Instead, the evidence showed only that the Town had not yet taken enforcement steps against Konzelmann’s specific non-compliant use. That shortcoming, by itself, was not enough to justify extraordinary remedies against the municipality.

Outcome and implications

In the end, the court concluded that Brox already had an effective remedy for the zoning contraventions: the consent order against Konzelmann. That order declares that Konzelmann’s 2024–2025 outdoor events breached the zoning by-law and site plan, and it permanently restrains the winery from conducting any land use inconsistent with those instruments or with any applicable Alcohol and Gaming Commission licence. Any future non-compliant use by Konzelmann would amount to a breach of a court order, exposing it to contempt proceedings and further judicial sanctions. Given this powerful remedy directly against the contravening landowner, the court found it unnecessary and legally unavailable to impose injunctive or mandatory orders on the Town itself. Accordingly, the application as against the Town of Niagara-on-the-Lake was dismissed. The judgment did not resolve costs on a quantified basis. Instead, the judge encouraged the parties to agree on costs and set out a timetable for brief written submissions if they could not settle the issue, leaving any final figure to be determined later or by agreement. As matters stand in this decision, Brox is successful in obtaining declaratory and injunctive relief against Konzelmann, while the Town succeeds in having the application against it dismissed, and no specific monetary award or total costs amount can be determined from the judgment.
