Yes, you're right! According to this NOC tutorial:
http://www5.hrsdc.gc.ca/noc/english/noc/2011/Tutorial.aspx#8, the first digit of an NOC code indicates the skill type and the second digit identifies the skill level. Chefs are NOC 6321, indicating skill level 3, which again looking at the tutorial, skill level 3 corresponds to skill level B. So that qualifies.
I've deleted the incorrect portion in my original post so as not to mislead anyone. Good catch and thanks for posting it. I stand corrected!
