Shortage of water in the future of Canada where can we get water?

Question

No water no life

Answer 1

Answer 2

recycling grey water, desalination plants.

Answer 3

Canada is one of those lucky places that will never run out of water, even clean water most likely will never run out.  There would have to be a drought of biblical proportions to cause all of the lakes and rivers to run dry.  If it did happen because we have three oceans surrounding the country desalinasation is a possibility also water treatment & recycling.  

Lastly if you are really in desperate shape you can make water all you need is hydrogen and oxigen and some electricity.  Hydrogen can come from any hydrocarbon source, oxigen is in the air pure would be better and electricity from photovoltaic cells.  two parts hydrogen, one part oxigen, zap, and you have a puddle.
