In this instance what's happening is that the national occupational classification system that we and ESDC rely on to administer both temporary worker programming and permanent resident programming is moving to the next iteration, the most updated iteration for it, NOC 2021. As it does this, the classifications are shifting. In particular, the truck driver occupation that I mentioned is shifting to be deemed a higher-skilled occupation.
The IRCC permanent residence programs governed under the express entry system aren't changing. It's simply that the occupations themselves are shifting around. The occupational classification system has over 500 occupations, and a number of others are being bumped up to become considered higher-skilled occupations.
