This article has been updated to include clarification from Health Canada that while it received more than 100 calls, not all were about incidents and injuries. Some called to ask questions about the recall. 

The article has also been corrected to say the products recalled were sold in Canada from January 2020 to October 2022, not January 2022 to October 2022.
