I believe the document is clear enough. One thing I would like to point out, and it's in the document as well, is that CARFAC and Regroupement des artistes en arts visuels held a meeting last week on taxes for artists, but it was more about how to do your taxes. They had specific guests from CRA and Revenu Québec. We can invite the same people. It's not clear whether or not they would be able to speak to the Status of the Artist Act precisely, but they might have other experts they can suggest at CRA and Revenu Québec.
It's for you to decide whether or not you want to invite them.
