Masks in Healthcare Facilities Update


As the province moves towards relaxing mask mandates, we wanted to take this opportunity to provide clarification for the public health guidelines that will be in place.

According to the changes in regulation that will take place on March 21, 2022, masking requirements will be removed "in most places except public transit, long-term care, retirement homes and other health-care settings, shelters, jails and congregate care and living settings, including homes for individuals with developmental disabilities".

Clinics that provide healthcare services will still be required to adhere to the masking guidelines.


We are OPEN during LOCKDOWN. All COVID protocols including contact tracing are strictly enforced. APPOINTMENTS ONLY, even for spectacle and contact lens pickups. Our in house lab can now do most single vision lenses on site, sometimes the same day.
