[1] In 1880, the Marquis of Lorne opened the first exhibition of the Canadian Academy; Watson's work was displayed and he was elected an Associate member.

[1] Watson married Roxanna (Roxa for short) Bechtel in 1881, and the couple moved into the Drake House at Doon.

[1] He was noted for his commitment to Canadian landscapes: he said at a lecture on "The Methods of Some Great Landscape Painters" at the University of Toronto in 1900: "there is at the bottom of each artistic conscience a love for the land of their birth... no immortal work has been done which has not as one of its promptings for its creation a feeling its creator had of having roots in his native land and being a product of its soil".

[8] The artists with whom Watson was most often associated were the English landscape painter John Constable (1776–1837) and such French Barbizon artists as Théodore Rousseau (1812–1867), Charles-François Daubigny (1817–1878), Narcisse Díaz de la Peña (1807–1876), Constant Troyon (1810–1865), Jules Dupré (1811–1889), and tangentially Jean-François Millet (1814–1875) because Watson didn`t share Millet`s focus on the nobility of human figures.

Homer Watson's letters, his unpublished manuscripts, and his paintings, drawings, and prints document the issues that most interested him as an artist.

Of his concerns, the commemoration of southern Ontario's pioneers and early settlers and the visual expression of Canadian regional and national identities locate Watson firmly within the milieu of many of his fellow artists of the time.

Two stamps of denominations 50 and 85 cents were issued depicting two of his works, Dawn in the Laurentides and The Flood Gates.

[12] An arterial road in Kitchener, which connects the Doon area to the main parts of the city, is named Homer Watson Boulevard.
