DIY Rat Rack - Canadian Water System Source?

Hi guys, I haven't posted much but gleaned tons of information from the members of the forum here. I currently own 2 southern pines, 11 corns snakes and one beautiful female captive hatched ball-python.

I've built the rat breeding rack and birthing rack that I found in these forums and would like to build a second birthing rack. I was wondering if anyone knows of a canadian source for the 3/16 vinyl tubing, 3/16 barbed L & T fittings and the 3/16 barbed shutoff valve that is installed in the bucket for the watering system?

Very much appreciated! Not that I have a problem with ordering from the states, I just get skewered on the brokerage fees the shipping companies charge to pay the taxes for me. Almost no company in the states will mail the items USPS.
