You are misreading what I wrote. Or maybe I was not clear enough.You are misreading the operations manual and trying to average the hours out. Based on your post, someone with part-time experience over 3 years would never qualify, which is flat out wrong and contrary to the advertised eligibility of the CEC class.
If you want to apply through CEC after 12 minth of work, you have to have between 1560 and 2080 hours worked. If you worked part-time 24 month and have 2080 hours worked- you can apply then, AFTER TWO years of working, not after ONE year.
It does not matter what people say on forums. What matters is operational manuals and knowledge of Canadian Labour laws , regulations and based on that- common sense.which is done on a week by week basis.
