Ontario Court: Finds Social Hosts Liable in Underage Drinking Case

In the Ontario case of *Foulidis v. Schummer*, Justice Dow recently decided that party hosts owed a duty of care to a party guest who was injured by a motor vehicle while leaving a 16th birthday party involving underage drinking, where the crowd ballooned to about 100 people.

This decision carries significant implications for the scope of social host liability in Ontario, particularly concerning events where minors consume alcohol. If the *Foulidis v. Schummer* ruling is affirmed on appeal, it would establish binding Court of Appeal authority, potentially broadening the circumstances under which social hosts could be held legally responsible for injuries sustained by guests. This could lead to increased scrutiny of hosts' responsibilities, compelling them to implement more stringent measures to ensure guest safety, especially when underage individuals are present and alcohol is consumed. The case highlights the inherent risks associated with hosting parties involving underage drinking, contrasting it with adult gatherings where the autonomy of guests is often emphasized.

Social host liability in Canada is primarily governed by the common law of negligence, which requires establishing a duty of care, a breach of that duty, causation, and damages. While commercial establishments have a well-defined duty of care to patrons, the extent of this duty for social hosts has historically been less clear and subject to evolving judicial interpretation. The excerpt references *Wardak v. Froom* (2017) as a regularly cited case in this area, indicating a developing body of jurisprudence. The *Foulidis* decision is contrasted with *Peterson v. Anderson* from Nova Scotia, where liability was not found, underscoring the fact-specific nature of these cases and potential jurisdictional differences. The fact that *Foulidis* is currently under appeal means its precedential value is not yet final, but its potential impact is substantial.

The key parties involved include Justice Dow, who rendered the decision in *Foulidis v. Schummer*, and Justice Smith, who decided *Peterson v. Anderson*. The specific party hosts and the injured guest in *Foulidis v. Schummer* are central to the Ontario case. Carr Hatch of Thomson Rogers LLP is mentioned as having represented plaintiffs in the earlier *Wardak v. Froom* case. The Ontario Court of Appeal will be a critical party as it reviews the *Foulidis* decision, and its ruling will shape future interpretations of social host liability in the province.

Legal practitioners advising individuals or organizations that host social events, particularly those where alcohol might be consumed by minors, must closely monitor the outcome of the *Foulidis v. Schummer* appeal. If the decision is upheld, it will reinforce the need for social hosts to take proactive and comprehensive measures to ensure guest safety, especially regarding the prevention of underage drinking and the safe departure of guests from the premises. Businesses and individuals hosting events should review their liability insurance coverage and consider implementing stricter controls over alcohol access, guest supervision, and transportation arrangements to mitigate potential negligence claims. The distinction between hosting for minors versus adults, as highlighted in the excerpt, remains a critical factor for risk assessment and legal advice.
