@Paul: Yes, you will have a hard time getting a visa if your postgraduate course in Canada is unrelated to your undergraduate degree. If you are a nurse, I suggest you get into a nursing program so that you can better defend your purpose in studying in Canada. Eligibility for PGWP is usually for students who spend at least 4 terms in Canada. Graduates can get a 3 year PGWP. I have not read of any information in CIC re: PGWP for 1-year course graduates. There are several ways of acquiring PR status. One of the is the PhD scheme. In Saskatchewan, they offer Masters graduates PR eligibility. If you are able to get PGWP, you can apply for the provincial nominee scheme once you secured at least 6 months of work experience plus a valid employment contract.
@Kimmy: I think you are only to prove that you can fund your first year of studies and 2.5M (Approx $60K) is over the top. Usually $30K is the average total costs for single students. But if you have dependents then that will be additional cost of around $10-15K/ year per family member. If you got more money to show, that will be great since the embassy will see you are study and not work in Canada and may increase your chances of landing a visa.
For those who plan to apply, better go for the paper-based application. I applied via the online facility last April 19 and until now I am yet to receive my request for medical examinations. Others who applied later than me via paper based application already have their medical requests.
