MS Cardiology

What MS Cardiology does

MS Cardiology is a private, community-based ambulatory cardiology clinic and diagnostic facility located at 491 Lawrence Ave West in North York, Toronto, Ontario. The clinic is staffed by 14 affiliated cardiologists, respirologists, and nephrologists who also hold staff or academic appointments at Mount Sinai Hospital, the University Health Network (Toronto General, Toronto Western), the University of Toronto, and several other GTA hospitals. Services span comprehensive cardiology consultations (general cardiology, pre-operative assessment, hypertension, heart failure, arrhythmias, pacemaker management) and a full suite of non-invasive cardiac diagnostics including echocardiography, 12-lead ECG, stress ECG, stress echocardiography, myocardial perfusion imaging, Holter monitoring (1–14 days), and 24-hour ambulatory blood pressure monitoring. A new Hypertension Clinic launched in July 2026 adds resistant-hypertension and cardio-renal-metabolic management.

The business model is anchored on Ontario's single-payer framework: the majority of consultations and diagnostic tests are OHIP-insured for eligible Ontario residents, with physicians billing the provincial schedule. Revenue diversification comes from fee-for-service charges to non-residents and third-party patients at OMA fee-guide rates, plus administrative fees (chart copies, work notes, insurance requests, no-show penalties). Customer acquisition is entirely referral-driven through multi-channel pathways (Accuro EMR integration, Ocean Provider Network, fax, email) and is supported by a physician-targeted monthly newsletter, MSC News. Same-day availability for echocardiography, Holter, and nuclear testing and hospital-network affiliations constitute the operational differentiators. There is no evidence of external investment, acquisitions, or multi-site expansion; the practice operates as an independent physician-owned entity serving the Greater Toronto Area.

Delivered by hospital-affiliated specialists in the community clinic.
• Echocardiography Non-invasive cardiac ultrasound procedure for adult patients referred for evaluation of heart structure and function, including chambers, valves, pericardium, and great vessels, providing anatomic and physiologic information about blood flow and pressure.
• 12-Lead Electrocardiogram (ECG) Standard 12-lead resting ECG for adult patients referred for assessment of heart rhythm, electrical conduction system, chamber size, muscle thickness, scar tissue, and ischemia.
• Stress ECG (Treadmill Exercise Test) Treadmill exercise stress test for adult patients requiring evaluation of heart rhythm, blood pressure, and symptoms under physical stress.
• Stress Echocardiography Stress echocardiogram combining treadmill exercise with echocardiographic imaging for adult patients requiring evaluation of cardiac function under stress.
• Contrast Stress Echocardiogram Stress echocardiogram performed with an echocardiographic contrast agent to enhance endocardial border definition and image quality for adult patients requiring improved visualization during stress imaging.
• Myocardial Perfusion Imaging (MPI) — Treadmill Exercise and Persantine Nuclear cardiology stress test for adult patients with suspected or known coronary artery disease, assessing myocardial blood flow at rest and during stress (treadmill or Persantine) to determine whether coronary disease is causing clinically significant ischemia.
• Holter Monitoring (24-Hour to 14-Day) Ambulatory cardiac rhythm monitoring service for adult patients requiring continuous ECG recording for 24 hours up to 14 days to detect intermittent arrhythmias.
• Event Monitoring Continuous ambulatory heart rhythm monitor worn for a week or longer for adult patients requiring detection of intermittent arrhythmias that may not be captured on shorter Holter recordings.
• Loop Event Monitoring Long-duration loop cardiac monitoring device for adult patients requiring up to three years of continuous rhythm recording to capture infrequent arrhythmias.
• 24-Hour Ambulatory Blood Pressure Monitoring 24-hour ambulatory blood pressure monitoring service for adult patients requiring assessment of diurnal and activity-related blood pressure variations using a portable device worn on a belt.
• Pacemaker Clinic Specialized pacemaker and cardiac device assessment and follow-up service for adult patients with implanted cardiac devices, delivered under the direction of the Director of Clinical Electrophysiology and Pacemaker Program at Mount Sinai Hospital.
• Hypertension Clinic Specialized outpatient clinic for adult patients with difficult-to-control or resistant hypertension, including secondary-cause investigations, cardiovascular and renal risk management, and integrated management of complex cardio-metabolic conditions (CKD, diabetes, dyslipidemia, obesity) and electrolyte abnormalities/proteinuria.
• Uninsured / Non-OHIP Services Fee-for-service cardiology consultations, diagnostic testing, and administrative services (chart copies, work notes, insurance requests, no-show fees) for non-OHIP-covered patients and third-party payers, priced per the OMA fee guide and disclosed with consent prior to delivery.
