Pediatricians are medical doctors who specialize in the care of children.

Pediatricians can treat children who have any type of problem, or they may specialize in specific areas, such as:

• Adolescent medicine (conditions and diseases common to teenagers).
• Cardiology (diseases and conditions of the heart and blood vessels).
• Developmental disorders (behaviour, communication, and mental disorders in children).
• Endocrinology (diseases of the endocrine glands, which regulate hormones).
• Gastroenterology (diseases of the digestive system).
• Infectious disease (complex infections).
• Nephrology (diseases of the kidney and urinary system).
• Oncology (cancer).

Pediatricians are certified by the Royal College of Physicians and Surgeons of Canada.
