Among architect-historians, William Thomas is recognized for being "one of the founders of the Canadian architectural profession." Thomas's work in Birmingham and Leamington Spa, England would have ensured him a modest place in English architectural history. However, it was for the mark he made on the fledgling communities of central and eastern Canada that he is best remembered.

His prodigious output during a seventeen-year career in Canada, dating from 1843 to 1860, included over one hundred buildings, many of which are still standing today. The significance of Thomas's contribution cannot be overestimated. His buildings became the foci of towns, housing the communities' religious, governmental, educational, commercial and cultural activities.

In drawings, prints and photographs of this period depicting Toronto, Quebec City, Hamilton, Halifax, London, Guelph, Chatham, and Niagara-on-the-Lake, we can see the direct and indirect effects of Thomas's work.

Glenn McArthur and Annie Szamosi's fresh and informative text surveys all of Thomas's known and attributed works. McArthur's superb photographs and watercolours are complemented by contemporary views, old photographs of demolished buildings, and original sketches. This publication is of special interest not only for the practising architect or historian but, with its strong visuals and informal style, accessible and entertaining for anyone eager to celebrate our architectural heritage.
