when I got 3" hose a few years back I couldn't find a supplier up here so I had to order from the US. As far as I know, no one is bringing these products affordably across so we have to do it ourselves.
The 2.5 (and 2") with the blue liner is what you want because of its flexibility. You won't find it up here unless someone ships it up. Best to bight the bullet, use UPS and split the shipping or if you can do what I do, find a shipping company that has a US address, have it shipped there, then they can ship it to you from there. Or ship it by US/Can Post and it will make it.
The bugger is that most stuff for cleaning is made in the US and we still have to pay a premium, even when our dollar is higher.
