Thank you for the comment and well wishes.

Chalk River shutting down was a huge blow to production capacity, as it alone supplied about 20% of the world's demand for radioisotopes. In fact, Chalk River shut down in 2016, but the license was extended for two years to keep it on hot standby solely because of its importance to nuclear medicine supply. When they finally permanently shut it down in March of 2018, I believe the reactor was over 61 years old!
