With the release of the Census 2016 Canadian data, we also upgraded to the 2016 Census geographies.
To Access Historical Data:
To access data and locations in 2011 and 2006 census geographic units you will need to activate Historical Mode.
To activate Historical Mode, (1) click on Manage Project and change the "Historical Geographic Boundaries' toggle from off to on (2). Specify your geographic Units (3/4), and select Done (5).
This is a project level setting, so activating Historical Mode in one project does not change this setting for any of your other projects.
