I'm admittedly more familiar with the Canadian and American bodies of law than the European one.
One lesson to take away is that the European approach, certainly for abuses of dominance, which includes excessive and unfair pricing, is much stricter than how Canada has approached it in the past. Perhaps there's a spiritual alignment, but the details and the structure of European law are different. It's much more pared back and less directive. It relies on nations such as Germany to pursue their own competition law policies.
It's very difficult to compare these approaches directly. If there's a connection in philosophy, that tighter approach to the abuse of dominance is in line.
