The first meetings of the Canadian Boiler Manufactures were held in the early 1920's at which the following representatives attended:

Mr. Alex Goldie, Goldie McCulloch

Mr. Logan Waterous, Waterous Engineering

Mr. William Inglis, John Inglis

Col. Ibbotson Leonard, E. Leonard & Sons

After a period of comparative inactivity, Logan Waterous arranged a meeting at Brandford of the Canadian members of the original Association of the United States Boiler Manufacturers. Those attending were:

Mr. Hugh McCulloch, Babcock-Wilcox & Goldie McCulloch

Mr. Logan Waterous, Waterous Engineering

Mr. William Inglis, John Inglis

Col. Ibbotson Leonard, E.Leonard & Sons

Mr. George Macnoe, Foster Wheeler

At this meeting, Logan Waterous suggested that the association be revitalized and it was agreed he should act as Chairman and Hugh McCulloch agreed to act as honorary secretary, with his duties being confined to distribution to the members of Minutes of Meetings. Subsequently, this became too onerous and Mr. Jos T. Crowder was engaged as a paid secretary. The main interest of all concerned at that time was H.R.T. Boilers.
