Well you have allowed them to process your application that means you will not be entitled to refund of fees that you have paid ,if you wanted to withdraw your case now. There is a huge backlog and CIC is changing rules for immigration. Wait & see what happens after the elections? A clear policy however will be in public once the elections are over.
If the Conservatives and Prime Minister Stephen Harper are re-elected, their new immigration priorities (which are, as yet unknown to the public) will finally be put into practice. If not, other political parties plan to repeal the amendments and introduce their own strategies for modernizing and streamlining the Canadian immigration system.
Good luck
