Several years back I was backpacking around Asia and that's where I saw this "plastic" money. I thought they were fantastic, the paper stuff around was falling apart yet here was something that I could keep in my board shorts, going swimming with, not worry about someone stealing it from my wallet that I had to leave at the beach, and I could then use it straight away without to individually dry them out again! Or putting it through the washing machine :) I didn't realise Canada had them too! Kinda surprised more countries are not using them, the security features (like the see through window) must be a lot harder to replicate, as well as looking pretty cool!
