What are the responsibilites of canadian judges in Canada?

Answer 1

Here's a great transcript of an interview concerning the topic that will answer the question:

Here is part of it. For the rest, click the link in sources.
"... Judges may be more respectful of human rights than politicians, and they may be less. Judges are drawn from lawyers, indeed from the legal elite. Without overgeneralizing, I think I can say that you become a part of the elite of the legal profession by being a handmaiden of the business establishment. When I practised law, my work came from business. For the most part, it was small business because big business didn't look upon me, as a former CCF cabinet minister, with favour. Some small businessmen didn't care. But still, my clientele was hardly a cross section of the electorate.

So judges are members of the legal elite, and therefore handmaidens of the business establishment, who are then appointed by the same politicians we are supposed to be suspicious of.

Judges are not accountable to the public. They are not supposed to be accountable to the public: that is what judicial independence means. They make their decisions on the basis of information provided to them by the parties to a particular lawsuit. That information is supposed to be narrowly focused on the disagreements between the parties to the suit...."

Answer 2

Judges are the agents of the government for the proper administration of justice.
