What others have said and I have a bit more to add. I assume you are talking about foreign work experience (i.e., work exp outside of Canada). From what I understand you can get the max 50 CRS points for foreign work experience ("transferability" points) if you have at least 3 years of fulltime work experience in NOC 0, A or B and (this and is very important) CLB 8 and above on your English language test components. Seniors can correct me if I'm wrong. All the best, friend.
