In the twenties, a modest expansion of Ottawa cricket took place. Three new clubs, Defense (formerly Militia), Christ Church Cathedral and New Edinburgh were formed and they still operate at the present time. In order to organize the cricket, which was now on League scale, the Ottawa Valley Cricket Council had been formed in 1920, the original constitution of which was drawn up in 1923.

A Governor-General of the inter-war period who took a keen interest in Ottawa cricket was Lord Willingdon who had been a member for four years in the Cambridge University XI.

The second World War posed serious problems for the administrators of the game in Ottawa, not the least of which was the loss of so many players. The situation was, however, saved by the influx of Commonwealth players who were serving in the armed forces. Much was owed, too, to the encouragement of Lord Athlone, the Governor-General, who donated trophies for annual competition in batting, bowling and fielding.

The Ottawa Valley Cricket Council is now the smallest of the five leagues in the Ontario Cricket Association and nobody will pretend that cricket now plays a significant part in the life of Canada?s capital or that its expansion, such as it has been, has kept pace with the growth of the City itself. It has, however, continuously provided a great source of enjoyment for many persons in beautiful surroundings and over a long period of time. At Rideau Hall, Ottawa posses a ground which has a setting as fine as any in Canada, of not in the world, and the game has a long and honorable history, which is intimately linked with successive Governors- General.
