Program Structure

PGY 1: Medical microbiology is a five-year program with the first year structured for successful completion of MCCQE Part II. This year consists of:

  • Three months medical subspecialties
  • Four months general internal medicine
  • Two months infectious diseases
  • One month general surgery
  • One month surgical subspecialty

PGY 2-4: The PGY 2 year is an additional year of clinical training with an emphasis on infectious diseases. The trainee then completes two years (PGY 3 and 4) of core microbiology including training in the laboratories of adult hospitals, and at the Hospital for Sick Children.

This will cover:

  • bacteriology
  • virology
  • serology
  • mycology
  • molecular diagnostics

Additional training in parasitology, mycology, mycobacteriology and reference microbiology will be carried out at the Public Health Laboratory.

PGY 5: The final year of training is planned to provide further experience in microbiology and the trainee accepts a greater level of responsibility. Dedicated research experience is strongly encouraged in this year although research projects are expected at all levels of training. Major research cannot be provided within the time limits of this program and trainees are advised to consolidate and expand their research skills by additional training following completion of the program.

The research interests of members of the division of medical microbiology are diverse and include:

  • pathogenesis and epidemiology of a variety of bacterial and viral diseases
  • antimicrobial resistance
  • epidemiology of hospital-acquired infections
  • molecular epidemiology
  • malaria

Residents are strongly encouraged to participate in research activities and to present and publish their results.

Applying to the Program


Candidates with Canadian Citizenship or Permament Residency must apply to the Laboratory Medicine Program through the Canadian Resident Matching Service (CaRMS). Basic eligibility criteria for the program can be viewed at the CaRMs website:

Selection Criteria

Demonstrated interest/experience in microbiology either as an undergraduate or during medical school may be helpful but is not essential. The main decision will be based on:

  • the academic record of the applicant
  • the candidate’s demonstrated commitment to the discipline of medical microbiology
  • reference letters
  • interview results

Given the large number of applicants each year, we are not able to offer an interview to all candidates. Personal interviews are offered to candidates based on the criteria listed above and are mandatory for admission to the program.

International Medical Graduates accepted into the program will have access to the same opportunities, training and experience as Canadian Medical Graduates.
