Mayfair remains open for all services with the following safety protocols:

  • Patients are required to wear surgical-type masks at all times while in our clinics to minimize the potential spread of infection from someone who is infected, and for those who may have COVID-19 before they experience symptoms themselves. If the mask you are wearing when you come for your appointment is not a surgical mask, we will provide you with one.
  • Increased health and safety protocols, including isolation areas for patients with cold or flu-like symptoms and/or risks of exposure.
  • Screening questions for patients at check-in.

Market Mall is the fourth Mayfair Diagnostics clinic to feature the GE Senographe Pristina Dueta mammography system, which Mayfair Diagnostics was the first to bring to Western Canada.

You can find us on the third floor of the Market Mall Professional Building. We’re just across the parking lot from Hudson’s Bay. Our location has lots of free parking, and there’s a medical laboratory close by.
