I found this today in the OECD 'Country Notes' for Canada.
The Recommendations section suggests to me that some occupations, perhaps those like Personal Care Workers, might find it difficult to become recognised in the years ahead. Others may well lose their recognition. I would suggest that this is a way of making it easier for employers to bring unqualified people into the workplace.
Although the 'Red Seal' may appear to be a benefit to tradespeople it also obviously has the tendency to reduce labour costs overall by increasing the supply of labour where it might otherwise have been short.
I doubt that these changes are intended to benefit working people.
