National Multiple Births Day (May 28) Published: ()

Multiple births mean the birth of more than one baby at a time: a birth of twins, triplets, or more! As unique as these births are, they also face more challenges: higher risk of premature birth, low birth weight and neonatal death (meaning death before a child is one month old). Due to a greater risk of abnormal cognitive development and learning disabilities, multiple birth newborns require careful neuro-developmental follow-ups. Families with multiple births face increased physical, psycho-social financial challenges; therefore, their needs with respect to health, education and social services are different from families with single born children.

The Public Health Agency of Canada’s Canadian Perinatal Surveillance System (CPSS) monitors and reports on national estimates and trends of perinatal health indicators, including multiple birth rates. Please note that the data presented below excludes Quebec.

Almost 2/3 of all multiple births are delivered through cesarean section, due to higher risk of complications and premature birth. [CIHI-DAD, 2006–2015]
