Note: Only fetal deaths where the product of conception has a birth weight of 500 grams or more or the duration of pregnancy is 20 weeks or longer are registered in Canada.
Source: Canadian Vital Statistics, Birth, Death and Stillbirth Databases
Note: During the production of each year's birth/death/stillbirth statistics, data from previous years may be revised to reflect any updates or changes that have been received from the provincial and territorial vital statistics registrars.2017, 2018, 2019 and 2020 data for Yukon are not available.Due to improvements in methodology and timeliness, the duration of data collection has been shortened compared to previous years. As a result, there may have been fewer deaths captured by the time of the release. Most provinces and the three territories require a stillbirth with a gestational age of 20 weeks or more or a birth weight of at least 500 grams to be registered. In Quebec (as well as in Saskatchewan prior to 2001 and in New Brunswick prior to November 1996), only fetal deaths (stillbirths) weighing 500 or more grams must be reported, regardless of the gestational period. Until 1997, only stillbirths with gestational periods of 20 weeks or more were required to be registered in Prince Edward Island, regardless of birth weight.Stillbirth data are tabulated according to the mother's usual place of residence.The geographic distribution of deaths in this table is based on the deceased's usual place of residence.Nunavut and the Northwest Territories (excluding Nunavut) came into existence on April 1, 1999. Data for these two territories are shown combined and separated for 1999 and separated from 2000 on. Historical data prior to 1999 are shown for the two territories combined as the Northwest Territories including Nunavut" series; it was terminated in 1999. The vital statistics data that pertain to these territories for 1999 were previously published on the basis of the legal definition of each territoryLate fetal death refers to a stillbirth of 28 or more weeks of gestation, excluding unknown gestational age.

Due to improvements in methodology and timeliness, the duration of data collection has been shortened compared to previous years. As a result, there may have been fewer births and stillbirths captured by the time of the release. The 2017 and 2018 data were revised on September 29, 2020. As a result of delays with birth registrations, fewer births have been captured to date for Manitoba in 2020.

Starting with the 2013 reference year, a new automated coding system was used to select the underlying cause of death. In 2017, an updated version of this coding system was implemented. 2017, 2018, 2019 and 2020 data for Yukon are not available.

Neonatal deaths

Note: During the production of each year's birth/death/stillbirth statistics, data from previous years may be revised to reflect any updates or changes that have been received from the provincial and territorial vital statistics registrars. 2017 to 2020 data for Yukon are not available. Due to improvements in methodology and timeliness, the duration of data collection has been shortened compared to previous years. As a result, there may have been fewer births and stillbirths captured by the time of the release. The 2017 and 2018 data were revised on September 29, 2020. As a result of delays with birth registrations, fewer births have been captured to date for Manitoba in 2020. The geographic distribution of live births in this table is based on the mother's usual place of residence.
