What are the Liberals/Green Party/Bloc Quebecois planning on doing for Canadian taxation?

I'm writing a paper on what the 5 parties are supporting for taxation. It's due in 2 days and I only have stuff for Conservatives and NDP. I have been looking up for about a week and i can't find anything that's good.ergg.... I need help.... giving links to good websites would be helpful. BUT don't give the the websites like Liberal.ca (like the regular websites) i checked there and there really isn't anything useful....
