That's an excellent question.
In an ideal world, all the Court of Appeal judgments, at least, would be translated. The mere fact that these cases have made it to the Court of Appeal means they carry a certain degree of importance. Three, sometimes five, judges have considered the questions of law, so the court's judgments are worthy of being disseminated.
I'm a lawyer at Fasken Martineau, and when I joined the privacy group, the Personal Information Protection and Electronic Documents Act, or PIPEDA, was coming into force. Quebec had already had protection of personal information legislation in place for 10 years, and the federal commissioner called upon us to educate English-speaking Canada on the body of case law that Quebec had built in 10 years, since the decisions had never been made accessible.
It was the federal commissioner's idea to take that step in that context. It was a small initiative involving a sliver of the decisions rendered. Unless a myriad of initiatives like that one are undertaken in each area of law, more translation resources will be necessary.
