Avoid the rookie mistake of ordering "cement" or that you want to "pour some cement.
Cement is the cementitious material that bonds the aggregate together in Portland Cement Concrete. We do not "pour" concrete, we place it. Enough water to make it pourable kills the strength of the concrete by increasing the water/cement ratio. One can add all the joints you want, but remember that concrete does two thing. It gets hard and it cracks.
Seeing that you are in Canada, I strongly suggest air-entrainment in the concrete and for heavens sake, avoid salt for at least a couple of years.
