I don't believe it is solely a Quebec issue, and I don't believe it would apply differently in any province.
This issue that has come up has involved incorporated specialists, whether they are engineers...and other situations perhaps. A backhoe operator having the cost of his own tools, his own backhoe, would be a lot different from an employee backhoe operator. It wouldn't be typical for an employer of employees who operate heavy equipment in the oil patch or Fort McMurray to expect them to bring their own tools or equipment to work. That could be one difference. With high-tech, maybe it isn't as apparent that you would have a correlation there.
But I can assure you that it's not a Quebec issue. We have had litigation and reviews of individuals who might be considered personal services businesses in all provinces.
