Although he is not officially a member of the Group of Seven, Tom Thompson is the most emblematic and influential artist in the movement. Talented self-taught, he is an outdoor painter and an insatiable explorer who constantly pushes others to paint the wild landscapes of the North. Drowned in 1917 in the midst of Canoe Lake, Tom Thompson will not participate in the nascent venture of the Group, but his friends never had the slightest doubt that, had he remained alive, he would have taken part in the adventure, as confirmed Harris:
"I counted Tom Thomson as a member, even if the group's name was given after his death, he was nevertheless essential to the movement, an integral part of its beginning and its development, in the same way as its other members."
"THE CONTENTS OF A DRUNKARD'S STOMACH"
Inclined to develop a nationalist and autochthonous painting, the Group of Seven soon claimed to represent the National School of Canada.
According to these artists, the wild nature of their country requires to be represented in a style more impertinent and more vigorous, in much more vivid colors, than the classic and academic landscape paintings.
Canada, a vast and wild land full of vitality, must be represented in a style that fuels its own qualities.
The paintings contemplate magnificent and powerful visions of rivers, lakes and forests in areas where the presence of man is rare, or even totally absent.
Two events will definitely mark the style of the Group of Seven. Alexander Jackson and Frederick Varley participate in the First World War. Once in Europe, they took the opportunity to study the movements and works of post-impressionists and neo-impressionists.
The local scenes of horrors will be found later in their compositions, especially in the use of dead trees and devastated or rugged landscapes. The most significant event took place earlier in 1912 when MacDonald and Harris visited an exhibition of Scandinavian contemporary paintings in Buffalo.
The Group's stylistic research will definitely take a new direction. Struck by the Scandinavian approach, which uses light to sublimate the Nordic landscapes, they deduce that these paintings could also represent the great nature of their Canada.
After their first exhibition in 1920, critics poured on the Group's paintings which look “the contents of a drunkard's stomach” and which "represent contempt of good morals". But their work is unconditionally supported by Eric Brown, director of the The National Gallery of Canada, who makes sure that paintings are visible at major Canadian exhibitions and at the Wembley exhibition in the UK, and he quickly stops the critics.
The years between 1925 and 1931 defined more deeply the importance of the subject, considering the latter as a criterion of Canadian national painting. Following a series of expeditions, ever farther and ever more northerly, the members of the Group of Seven perpetually sought out the most imbued corners of forms, atmosphere, soul and spirituality.
Strongly convinced that the soul of Canada must be felt in its very essence, they have concretized their vision of a northern nation fully embracing its vast wilderness.
Separated in 1933, the Group of Seven gave birth to a new movement giving Art a simpler, more accessible and more expressive meaning: the Group of Canadian Painters.
The latter, composed mainly of young artists, will have contributed to the renown of the Group of Seven by democratizing the legacy of these painters of the wild North, which today occupy a prominent place at the heart of Canadian history.
