I would just add that it's a determination of whether you are considered to be an employee or self-employed.
In terms of whether that then leads to the designation as a personal services business, there are a couple of other factors to consider. The legislation says, if not for the corporation, you would have been considered an employee—those are the factors that Lucie just talked about—but also, you or someone related to you has to own more than 10% of the shares of that corporation, and if you don't have more than five full-time employees throughout the year, that then signifies that you are a personal services business.
