Current Top 10
The Specialists in Poison Information document every call received by the Ontario Poison Centre. This data:
- Provides valuable information that can guide future treatment recommendations.
- Allows the Ontario Poison Centre to identify emerging trends around substances causing harm.
- Prevents unnecessary poisonous exposures and potential deaths.
The Ontario Poison Centre regularly determines "Top 10" lists, identifying the top ten most common types of exposures managed by the Specialists in Poison Information. Over time, these lists have changed, reflecting regulatory changes and other trends happening in Ontario. For instance, pain-relievers containing aspirin used to be one of the most common exposures until child-resistant packaging was introduced in the 1970s. Now, because of safer packaging and the availability of aspirin-free alternative pain relievers on the market, aspirin exposures rarely occur.
Top 10 - All Ages
1. Pain Relievers - Medicines that are given to relieve pain are the most common exposure that the Ontario Poison Centre deals with. These pain relievers are most commonly made of acetaminophen or ibuprofen.
2. Sleeping Medicines - Many people take a pill to help them fall asleep. These medicines are commonly found in people's homes and are commonly involved in overdose situations.

8. Foreign Bodies - These are actually non-poisonous substances that are just not meant to be swallowed. They may not be poisonous, but could still cause harm.
9. Antihistamine Medicines - These medicines are commonly found in pills that you would take for allergies.
