Superior Court Denies Serious Injury Claim of Woman Who Drank Cleaning Liquid in McDonald’s Cup
In a recent ruling, the Ontario Superior Court of Justice addressed a case involving a woman who accidentally ingested a cleaning solution from a cup she received at a McDonald’s drive-thru. The incident occurred when McDonald’s staff inadvertently served a delimer solution—a chemical used to clean and descale coffee machines—in a cup given to the plaintiff.
While McDonald’s admitted liability for the incident, the company contested the severity of the injuries claimed by the plaintiff. The court ultimately awarded the woman $5,000 in general damages, along with pre-judgment interest, but rejected her claims of serious or long-term physical harm.
The court acknowledged that the woman experienced immediate distress and short-term symptoms, including an unpleasant taste, upset stomach, nausea, vomiting, and diarrhea. These reactions were recognized as her body’s response to expelling the ingested substance. However, the court found insufficient evidence to link the delimer solution to the more severe injuries she alleged, such as chemical burns, persistent pain, or voice-related issues like muscle tension dysphonia (MTD).
McDonald’s argued that the cleaning solution was food-safe and had a pH level comparable to lemon juice, making it unlikely to cause the serious injuries described by the plaintiff. The court agreed, stating that while the experience was undoubtedly distressing, the long-term physical effects claimed by the woman could not be proven on a balance of probabilities.
The court also considered alternative explanations for the plaintiff’s ongoing symptoms, such as acid reflux from excessive vomiting, smoking, and frequent voice use. These factors, the court suggested, could have contributed to or caused some of the symptoms she experienced.
While the court accepted that the incident caused temporary emotional distress and acute physical discomfort, it concluded that the claim of serious or lasting physical injury lacked sufficient evidence. The $5,000 award reflected the immediate harm and emotional impact but did not account for the more severe injuries alleged by the plaintiff.

Court Considers Emotional and Psychological Impact
The Ontario Superior Court of Justice also addressed the emotional and psychological impact of the incident on the plaintiff. The court recognized that the woman experienced significant distress immediately after ingesting the delimer solution. Upon realizing she had consumed a cleaning chemical, she contacted poison control and visited the hospital multiple times seeking reassurance, which the court acknowledged as evidence of her acute emotional response.
While the court accepted that the incident caused temporary emotional distress and acute physical discomfort, it found no evidence to support the claim of long-term psychological harm. The court noted that the plaintiff’s emotional state was understandably unsettled and anxious in the immediate aftermath but did not persist beyond the initial shock of the incident.
The court’s decision also highlighted the importance of the legal “but for” test in determining causation. The test examines whether the alleged injuries would have occurred “but for” the incident in question. In this case, the court was not convinced that the plaintiff’s claimed injuries, such as chemical burns or muscle tension dysphonia (MTD), were directly attributable to the ingestion of the delimer solution.
The court suggested that other factors, such as acid reflux from excessive vomiting, smoking, and frequent use of her voice, could have contributed to or caused some of the ongoing symptoms, particularly MTD. These alternative explanations undermined the plaintiff’s claim of a direct link between the incident and her alleged long-term injuries.
This ruling has implications for personal injury claims involving food establishments and cleaning substances. It underscores the need for plaintiffs to provide robust evidence linking the incident to their alleged injuries. In this case, the court’s decision balanced the immediate harm caused by the incident with the lack of evidence supporting more severe or lasting consequences.

Conclusion
The Ontario Superior Court of Justice’s decision in this case underscores the importance of evidence-based claims in personal injury cases. While the court acknowledged the immediate emotional and psychological distress caused by the incident, it found no evidence to support the plaintiff’s claims of long-term psychological harm or severe physical injuries. The ruling highlights the significance of the legal “but for” test in establishing causation and the need for plaintiffs to provide robust evidence linking the incident to their alleged injuries.
The court’s decision also emphasizes that alternative explanations for symptoms, such as pre-existing conditions or unrelated factors, can undermine claims of direct causation. This ruling serves as a precedent for future cases involving food establishments and cleaning substances, reminding plaintiffs and their legal teams of the high burden of proof required in such claims.
