This paper is devoted to perception of the February Revolution, the October revolution and the Civil War in Russia in Canadian historiography. The paper considers, firstly, works of historians - Canadian citizens, secondly, works of scientists from other countries who have worked in Canada for a long time and, thirdly, works of foreigners, who published in Canadian scientific journals. All of the above works can be divided into three groups. Firstly, these are fundamental works on the history of the Russian Revolution and Civil War. Secondly, these are works devoted to foreign intervention in Russia and Canadian participation of Canada in this intervention. Thirdly, these are works relating to other particular aspects of this subject. The authors of all considered works refer to the February Revolution as an important step for democracy in Russia. Canadian historiography mainly condemns the October Revolution and criticizes Bolsheviks for authoritarianism and radicalism. The attitude of Canadian scientists to the White Guards is ambiguous. On the one hand, there is a certain sympathy for the Whites as allies of the Entente (and Canada). But on the other hand, the Whites are condemned for their ill-conceived domestic policies and for inability to reach a compromise with each other. The Canadian historiography of the 1917-1922 events in Russia is now practically unexplored, and therefore it is of scientific interest.
