Welcome to Mayfair DiagnosticsThe CORE

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.
  • Please note that all entrances to the mall are open at 7:00 a.m.
  • 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.

If you live or work in the heart of downtown Calgary, our location in the CORE Shopping Centre is the best place to come for your medical imaging needs. The plus 15 makes getting to and from your appointment convenient and if you feel like treating yourself after your appointment, there are many fantastic shops and restaurants nearby.
