Not an Albertan or Canadian. Could just be my lack of knowledge but the 7 and 8th questions seem reasonable to me? The explanations seem to be lacking.
7: Letting provincial governments to appoint provincial King's Bench and Appeals courts. What's the rationale for the federal government appointing provincial justices? Are these courts responsible just for provincial law, or all law?
8: Abolishing unelected federal Senate. What are these 'constitutional implications' that are so extreme? Why is the existence of an unelected senate so readily accepted because it's already there and it would be hard to remove? Can't another institution take its place as a check on federal power?
