Effective today (November 19, 2020), new orders and restrictions were announced by the PHO, including orders about mask use.
Masks (non-medical) must by worn by everyone in all shared indoor settings and workplaces unless they are in a screened or private work area.
For Physical Therapists (PTs), this means that masks must be worn both by PTs and patients, including in the treatment room, unless either or both is physically unable to wear a mask.
