Why did some 2016 Census variables at the Federal Electoral District (FED) level change between the 2019 and 2020 data releases?

Answer

In the 2020 data release, Environics Analytics, the company that provides Esri advanced Canadian deomgraphic data, implemented a change in the methodology used to apportion the 2016 CensusPlus data at the Federal Electoral Districts (FED) geography level.
