I actually did about 30+ percent of what is indicated in duties of Noc 7611. And my employer may give me a letter and confirm that I was performing many duties of labourer
But is it allowed by Canadian system to perform all duties of a plumber and like 50 percent of duties of construction helper? In our country the system is a little bit different, for example an electrician may mix, pour and spread materials such as concrete by himself, may load and unload construction materials, and move materials to work areas, etc.
