From my experience with the different immigration departments, as well as being an immigration consultant, COVID-19 has revealed that all skill levels are equally important, low-skilled, high-skilled, are all important. From truck drivers to hotel cleaners to meat processors and those providing services in health care, Canadians rely on temporary foreign workers for many essential services. These temporary foreign workers come as individuals on post-grad work permits. They may be in Canada on working holiday work permits or they may be tied to a labour market impact assessment, to name just a few. I think all levels are really important as Canadians and permanent residents are reluctant to take certain occupations. For example, a long-haul truck driver has an extremely difficult job and not many Canadians or permanent residents are necessarily lining up for those positions.
