Guys, I think that this is not true. Just look at the eligibility criteria for CEC:
You need to meet these requirements to apply under the Canadian Experience Class. You must:
plan to live outside the province of Quebec
have at least 12 months of full-time (or an equal amount in part-time) skilled work experience in Canada in the three years before you apply,
have gained your experience in Canada with the proper authorization
meet the required language levels needed for your job for each language ability (speaking, reading, writing, and listening).
Skilled work experience
According to the Canadian National Occupational Classification (NOC), skilled work experience means:
Managerial jobs (NOC skill type 0)
Professional jobs (NOC skill type A)
Technical jobs and skilled trades (NOC skill type B)
You must have at least 12 months of full-time, or an equal amount in part-time, skilled work experience. Full-time work means at least 30 hours of paid work per week.
So, where does it say that postdocs cannot apply for the CEC and the stipend is not considered as a income sourse???? Like others, we pay taxes, we work under the work permit, we are listed under the NOC 4011.
