Atlas of Canada

Summary

This article traces the century-long development of the Atlas of Canada from its first publication in 1906 to its mature online form in the early twenty-first century. Drawing on publication histories, it compares successive editions in terms of responsible institutions, map scales, thematic coverage, formats, and intended users. The first four editions progressively broadened their treatment of national development and cultural identity through printed maps. Amid organizational restructuring, fiscal constraint, and rapid computerization, the fifth edition shifted toward a digital national atlas information system. Launched in 1999 and substantially renewed in 2006, the sixth edition became a web-based platform for educators and the public, offering more than 600 interactive thematic layers, over 1,450 maps, and nationwide topographic and toponymic information. This evolution demonstrates the transformation of a national atlas into a user-centered, collaborative geographic information service.
