What you earn and what it costs to get there.
Typical net
$550,000
Part-time or new
$350,000
Interventional, busy
$750,000
CIHI (Canadian Institute for Health Information) reports average gross payments of about $695,000 a year for cardiology (2023 to 2024), the highest of any medical specialty in its tables, with a median near $600,000. After overhead most cardiologists net $450,000 to $650,000. Procedure-heavy cardiologists earn the most. It varies by province and by how you bill.
$65,000 to $95,000
Salary across 6 years: 3 of internal medicine, then 3 of cardiology, rising each year
Paid employees with benefits and a union contract. Year 6 residents are at the top of the pay grid.
Highest for interventional
Stents, ablations and device implants bill far more than clinic visits
A general cardiologist running clinics and reading heart tests still earns well. The very top incomes come from the catheterization lab and heavy call.
Tuition, fees, exams and kit. Not rent, food or travel
The low end is three undergraduate years at cheaper provincial tuition, a three year medical degree, one sitting of the MCAT (Medical College Admission Test), and the exam fees. The high end is four undergraduate years and four medical school years at the top of the range, plus two specialty exams, one in internal medicine and one in cardiology, at several thousand dollars each. The six residency years after medical school are paid, so they add no tuition and let many people pay debt down before practice. Typical debt at graduation is $80,000 to $150,000.
Typical debt at the end of medical school is $80,000 to $150,000. Six paid residency years mean you can pay a lot of it down before practice.
Pension only if salaried
Most are self-employed. Academic cardiologists on hospital contracts sometimes get a pension. Ontario residents are in HOOPP (the Healthcare of Ontario Pension Plan) during training.
Union contract during residency
Provincial residents' associations negotiate pay, call limits and leave.
Malpractice coverage
Through the CMPA (Canadian Medical Protective Association), mostly reimbursed by the province.
Professional corporation
Most provinces let doctors incorporate, which lowers taxes on money left in the business.
The exact path from high school to qualified.
You become an internal medicine doctor first, then a heart specialist.
High school
Grades 11 and 12
Top marks in biology, chemistry, math and English. You need a very high average for a science undergrad.
Bachelor's degree
3 to 4 years
Any major works. Keep a GPA (grade point average) above 3.8, volunteer, do research. Write the MCAT (medical school admission test).
Medical school, the MD (doctor of medicine)
3 to 4 years
Acceptance rates are 5% to 15%. Classes, then clinical rotations.
Internal medicine residency
3 years
Matched through CaRMS (the residency matching service). Hospital wards, the ICU (intensive care unit) and clinics. In year 3 you apply to the subspecialty match.
Cardiology residency, then certification
3 years
Heart clinics, the catheterization lab, echo and rhythm labs. Pass the Royal College exams to become FRCPC (Fellow of the Royal College of Physicians of Canada) and register with your provincial College of Physicians and Surgeons.
Biology and chemistry
Required for nearly every pre-med path.
Physics
The heart is a pump and the vessels are pipes. Pressure and flow matter. Also on the MCAT (medical school admission test).
Calculus and functions
English
You will explain risk to frightened people every day.
You need a licence from your provincial College of Physicians and Surgeons to practise, and Royal College certification in both internal medicine and cardiology. Both are national credentials, so moving provinces is mostly paperwork. Quebec requires working French. Cardiologists do not do open-heart surgery; that is a cardiac surgeon, a different path.
Things you don't need, but that help.
Most cardiologists add 1 to 2 more years after the 6-year residency.
Interventional cardiology
Open blocked arteries with stents through the wrist. Heart attack call at 3 a.m. Highest pay.
Electrophysiology
Heart rhythm problems. Ablations, pacemakers and defibrillators.
Advanced heart failure and transplant
The sickest hearts, mechanical pumps, transplant lists.
Echocardiography or cardiac imaging
Ultrasound, CT (computed tomography) and MRI (magnetic resonance imaging) of the heart. Fewer nights.
Research experience
Cardiology is research-heavy and programs notice publications.
Stamina
Fourteen years of training is a marathon. Athletes tend to cope well.
French
Opens Ottawa, New Brunswick and Quebec programs.
Comfort with data
Reading heart tracings is pattern recognition at speed.
Day to day, pros and cons, where you'd work.
Morning: round on heart patients in hospital, then a clinic of 15 to 25 people with chest pain, heart failure or rhythm problems. Afternoon: read a stack of echocardiograms and ECGs (electrocardiograms), or spend it in the catheterization lab threading wires into hearts. On call, a heart attack can page you any hour and you have 90 minutes to open the artery.
The good
The hard parts
Things people don't tell you.
In 1950, Canadian engineer John Hopps built the first external cardiac pacemaker at the University of Toronto, working with heart surgeon Wilfred Bigelow. Millions of people now live with a descendant of it in their chest.
Heart disease is the second leading cause of death in Canada after cancer. Deaths from heart attacks have fallen sharply since the 1980s thanks to stents, clot-busting drugs and statins.
Most Canadian cardiologists now open blocked heart arteries through a needle hole in the wrist. The patient is awake, talking, and often walks out the same day.
Six years after medical school, plus a fellowship, means many cardiologists start full practice at 33 or older. The pay makes up for it, but the years do not come back.
Last checked September 2026. Pay figures are typical full-time annual amounts in Canadian dollars, based on Government of Canada Job Bank wage data and published salary grids. They vary by province, employer and experience. Tuition is for domestic students.
