When I tried getting the DTaP separate the CLSC made a big deal, and they went until the ministry of health in QC, and they said not possible.
Why? Because people will be coming in for more visits, and they don't have enough time (or people) to be able to do this, so it's easier to have it all in one. I told the nurse: They care about gov. not about the people.
In the US it's all possible.
Part of free healthcare, they don't want to be burdened too much.
