Winterfox -please check if you're in the Specialized Worker category or Manager. If you are, then your limits are respectively 5 years and 7 years, and the cooling period is 1 year, instead of 4 more. I have actually done a lot of research on this, so if you tell me your exact scenario, I can help you.
NOTE: If you've only stayed in Canada in all these years, then YOU HAVE TO apply for EXTENSION from Canada. If you're planning to go back home and apply, it will be counted as a NEW app and your app will be rejected based on 1-continuous-year-outside-Canada-in-last-3-years rule... My story :'(
Please don't wait and repeat my case. Act now.
