I have not looked up the fare rules, but see lots of options in September and October, 2023, in my 8-day itinerary searches on Google Flights.

Example: YYZ-MUC, October 7-15, $3009 CAD -- many other destinations are $2900-3100 CAD

Based out of YQR, I found YQR-MUC for the same dates for $3500 CAD, which is excellent for any TATL ex-YQR, so fares will vary depending on Canadian departure city.

Edit to add: there seems to be availability at these fares from late May to December 7, 2023. A good time to book summer travel!
