Well the absolute CHEAPEST option is just to get a Toronto Public Library card and visit one of the many Toronto Public Libraries. All of them (until Rob "I'M On a diet so people won't call me a fat F--K Ford" puts a stop to it) have movies available to be borrowed. Some are pretty good recent hits. Star Trek 2009, Expendables, all available at various libraries.
Whether you choose to make copies of the movies you borrow I will leave up to you
You can also search the system and put holds on stuff you want and they will send it over when it's available to whatever library you specify. Toronto Public Library ROCKS. Enjoy it while you can!
