I'm not in a position to answer that. The CSIC regulator may be able to give more information to the second part of your question about how serious this is.
The biggest concern I have experienced is recruiters practising immigration law abroad and inside Canada. They also use the labour market opinion process to get access to employers. A recruiter in Alberta, let's say, would go to an employer in Saskatchewan and say, “I think I can obtain a labour market opinion for you”. That person probably has very little knowledge of immigration law, but uses this to move into the field of immigration.
In my view, recruiters trying to do immigration work inside and outside of Canada is my biggest concern.
