What about initiative and referendum, can the citizens start a ballot initiative like they do in california?
No.
That was another Reform proposal.
Canada and the US have political systems based on differing underlying fictions. The congressional fiction is that it is an expression of "popular sovereignty", a revolution from monarchical sovereignty whereas the parliamentary fiction is an expression of "parliamentary sovereignty", an evolution from monarchical sovereignty.
Both are fictions but the US one tends more toward populism than does the Canadian one.
