If you have been self employed, run a business or been at a senior management level, you may be able to get a Business Visa. With this you can set up a business in Canada and when you can show performance indicators within a 3 year period, you can then become a Permanent Residence.
If you have lots of money (minimum C$800,000), prove how you got it and how long it took you, you could get Permanent residency. You would have to invest $400,000 with the Canadian government, interest free for 5 yrs. There is an alternative.
