The methods for estimating mortality and death probability at advanced ages were changed to better acknowledge characteristics of death in advanced ages, particularly in terms of small sample sizes. These changes apply to the construction of life tables for the period 2005 to 2007 onward. The impact of these changes on life expectancy for Canada as a whole is minimal, with a difference of 0.07 years.
National estimates are available in 10-year intervals starting in 1920 and annually starting in 1979. Provincial/territorial estimates are available annually from 1979 to 2006. Separate estimates for Nunavut and the Northwest Territories are available annually from 1999 to 2006. From 1979 to 1999, estimates are available for the two territories combined as "Northwest Territories including Nunavut."
Estimates based on three years of pooled data are available at the provincial level from 1992 to 1994 onward; however, the territories are presented as a group for the period between 1992 to 1994 and 1997 to 1999.
Estimates based on three Due to improvements in methodology and timeliness, the duration of data collection has been shortened compared with previous years. As a result, there may have been fewer deaths captured by the time of the release. The 2017 data is therefore considered preliminary.
Estimates based on 3 years of pooled data are available at the regional level from 2000 to 2002 forward, with the most current data being for 2014 2015 to 20162017.
