Ya, I was totally worried when I ran out earlier this week. Walked into a Shoppers Drug Mart...the lady asked no questions. I just bought a whole box of 100 for 50 cents a piece. She laughed, told me people use them for injecting glue into busted furniture, decorating cakes, all kinds of crazy shit. No 23ga, but 22ga now works just fine for me. I guess Canada is good for some things after all...lol.
