Read the label on the back, not the box
Identification is the step most owners will get stuck on, because the obvious evidence is gone. The box went to recycling in 2022. The receipt is lost or was a gift receipt from someone else. Neither matters much here.
Health Canada says the model number is printed on the warning label on the product itself. Jupiter's notice is more precise: the product information is on the warning and product labels attached to the back of the item. Turn the nest over, find those labels, and compare the number against the table below. The UPC is a secondary check. Health Canada notes the UPC came on the packaging, so it is only useful if you kept the box.
Two further clues can help if a label has been cut off or washed illegible. The first is the brand: these were sold under the Simmons name as the Kozy and the Nido. The second is where they came from. According to the importer, the nests were sold by Walmart Canada, Toys "R" Us, Winners, Canadian Tire, Best Buy and specialty juvenile retailers across Canada. Health Canada's notice names no retailers at all, so that list exists only in the company's document. If you received a Simmons-branded nest as a shower gift between 2022 and this fall, the odds are reasonable that it came through one of those stores.
If the label is gone and you cannot rule the product out, treat it as recalled. The cost of a wrong "probably fine" is carried by the baby, not the owner.
Children's products recalls cluster around the same rooms of the house, and this one is not the only recent notice affecting a nursery. Homeowner.ca also covered the recall of Vevor retractable baby gates over an entrapment hazard.
