[1] He is best known for his paintings of Canadian genre scenes involving landscapes and outdoor life, which were as sought after in his own time as they are today.

Keating was under investigation by the Art and Antiques squad at Scotland Yard for selling several fake Krieghoffs in the UK, and he claimed to have painted several hundred of them, mostly in the 1950s.

Keating denied finding any of his pastiches in Thomson's collection, nor at the AGO, nor at any of several other Canadian fine art institutions he carefully scrutinized.

He professed relief that his vendetta against greedy art merchants had not tarnished the fine collections he felt privileged to tour and study over the course of his three-week visit.

[11][16][13] In February 1979, while giving evidence in his art fraud trial at the Old Bailey, he did say he was told in the 1950s that seventeen Krieghoffs in Lord Beaverbrook's collection were fakes by him.

The 10-minute film, directed by Colin Low and produced by Tom Daly, depicts 19th-century Québec life, as Krieghoff would have seen it, and uses his work to illustrate his source of inspiration.

[19] On July 7, 2000, Canada Post issued 'The Artist at Niagara, 1858, Cornelius Krieghoff' in the Masterpieces of Canadian art series.

This record was set by Mail boat landing at Quebec, a 17 by 24 inch oil painting on canvas sold November 20, 2006, at Sotheby's & Ritchies (Toronto).
