Sure. Because of particular procedural-level stuff that happens at the CRA at the moment, artists are disproportionately targeted for reassessments because by default they are not recognized by CRA as self-employed. The minute they declare any revenue as self-employed income, because they are business people and this is the appropriate way for them to declare it, the CRA tends to have a problem with that.
That starts a chain reaction, which often leads to artists.... They run their businesses by themselves. They don't have an accounting department. They are often simply not equipped to respond to the requests. They wind up paying the amount, even though by law they are not liable for it.
