The Canadian Century Research Infrastructure is a pan-Canadian, multi-disciplinary and multi-institutional effort to develop a set of interrelated databases centred on data from the 1911, 1921, 1931, 1941 and 1951 Canadian censuses. The long term plan is that these databases will be joined to other data that cover the periods from 1871 to 1901, and from 1961 to 2001.

The CCRI project successfully ran from 2003 to 2009, based at 7 university centres across Canada. Since its completion, the different components of the project are hosted in a number of different locations: the main site at the University of Alberta, as well as sites at CIEQ (Centre interuniversitaire d’études québécoises at Université Laval and Université du Québec à Trois-Rivières), and at the University of Toronto. Proposals are going forward to consolidate and enhance this work.

A gateway website is hosted at the University of Alberta.

Distribution of CCRI Geographic reference (GIS) layers:
The GIS layers have been completed for the CCRI project, and are available to researchers in
ESRI shapefile format. These are now available from the U of Alberta gateway website at:
