Under what immigration class do you want to apply for PR? If you are planning on applying under Canadian experience class, you need 2 years studies and 1 year work or just 2 years work. With a 2 year course, you can get a 3 year open work permit which will give you plenty of time to find a skilled job and work for one year before applying under CEC but with only a 1 year course, you can only get a 1 year open work permit.
