You can use standard compression fittings for tubing. Those are the brass fittings with the ferrule and nut, you just need to make sure to use the sleeves that slip inside the plastic tubing to reinforce it.

From my experience, the water pressure in Calgary varies from 70-90 psi on average with a few areas coming in as low as 45 psi, but that is uncommon. The maximum you should ever get is 100 in a residential area, there are pressure control valves in the water mains to limit it. Higher than that and household plumbing is more likely to have troubles, particularly the older it gets.
