Looking for small ice packs in Montreal/Canada (Example photos inside // Kinda urgent)

Anyone in Montreal/Canada know where I might be able to find small Ice Packs (Refrigerated gel packs) of any sort like the size in the photos?

I'm a tourist so I really don't know anything here in Montreal, I've tried Dollarama, Pharmaprix and Canadian Tire and they don't have any. I'm pretty troubled since that's what I used to keep my insulin cool throughout the day, but all the gel just leaked out a few hours ago. Thanks in advance.
