Start With the Canadian Institutions

Gagnon spent most of his career between Quebec and Paris, and the bulk of his estate ended up in Canadian public collections. That shapes where you should look. The National Gallery of Canada in Ottawa holds a substantial group of his paintings, drawings and prints, and its collection database is searchable by artist. The Musée national des beaux-arts du Québec holds work with a strong Quebec focus. The McMichael Canadian Art Collection in Kleinburg also counts him among its artists.

These databases vary in what they show. Some entries include high resolution images you can zoom into, which matters if you are studying his brushwork or the tonal structure of a winter landscape. Others list a work with minimal or no image, usually for rights or condition reasons. Expect gaps, and expect to check two or three sources before you have seen a given painting properly.

Free Guides and Aggregators

The Art Canada Institute publishes a free online guide to Gagnon, written with scholarly input and illustrated with works drawn from public collections. It is the fastest way to get a coherent overview, because the images are grouped and captioned rather than scattered across a database. For a reader who wants to understand the arc of the career before hunting individual pictures, it is the better first stop.

Aggregators fill the remaining gaps. WikiArt hosts a browsable selection of his works, and Wikimedia Commons carries images of works that are out of copyright or released under open licences. Auction house archives list works that have come to market, which is useful for seeing the range of his village scenes and winter subjects, though listings disappear over time. If you are weighing what kind of print would suit a room, the subjects guide for Gagnon's work the most recognizable Gagnon subjects pairs well with a browsing session.

Browsing Versus Buying

It helps to be clear about what each source is for. Museum databases let you study a work but not own it. Auction results tell you what originals fetch, which is a different market entirely from reproductions, and prices there reflect rarity, condition and provenance. If your goal is to live with a Gagnon image, a well made print of a public domain work is the practical route, and the choice between formats is mostly about the wall it hangs on. The comparison between canvas and framed formats canvas print versus framed poster covers that decision in detail.

A few works circulate widely in reproduction because they entered the public domain, so the same Charlevoix village scenes appear across multiple print sellers. That is not a bad thing. It means you can compare how different editions handle the warm ochres and deep blues before committing. For anyone still assembling a shortlist, browsing the archive of available editions the Auvrique archive shows what a properly presented catalogue looks like, even where a specific artist is not yet represented.
