The architecture in Canada has evolved to reflect both its European heritage and modern global trends while adapting to the country's environment. As Canada developed, architectural styles became a means to express its identity as an independent nation. This architectural development, especially in the 19^th and early 20^th centuries, was influenced by colonial styles from Great Britain and France. While French colonial was more prominent in Quebec, British styles influenced the rest of the country.

In this context, the adoption of 19th^-century Gothic Revival styles and Classical Revival styles of the early 20^th century became popular. Today, many of those buildings remain as prominent landmarks across the country and have become integral parts of the urban landscapes. This curated collection explores how Canadians are integrating traditional elements with modern materials like glass and steel. These efforts preserve the historical significance of the buildings while adapting them to meet the functional demands of modern life.
