Thank you for that excellent question, which I am unable to answer.
Nevertheless, I could readily find the answer to the question about tax credits. Some of my friends are artistic directors of Francophone theatres. Lorraine Pintal, for example, comes to mind. I'm sure I could obtain information that would be useful to you. I can get an answer for you within a few hours or by tomorrow.
Tax credits could be a form of assistance. There were several support measures introduced during the pandemic. For example, the ticket sales matching program which was widely used and enabled theatres to stay afloat even though audience sizes were seriously reduced. To ensure a more lasting recovery, longer-term measures could be considered. It's important to learn lessons from the pandemic.
