History Local lodge 1660 of the International Association of Machinists and Aerospace Workers (I.A.M.A.W.) was founded by workers of what was then Dominion Engineering Works of Lachine, a suburb of Montreal, in Quebec, Canada. We received our Charter in March of 1943, and signed our first contract with Dominion Engineering Works in March of 1944.

Over the years, our Lodge became a composite Lodge with the addition of Black McDonald in the sixties, followed by Zimcor, Bedarco, and Godfrey-Howden, some of these companies having since closed, or been renamed. In 1962 General Electric bought Dominion Engineering Works, and in 1984 they split up the company by selling the paper-making machine business to Valmet, of Finland. Dominion Engineering Works then became G. E. Hydro, which still remains our largest Bargaining Unit with approximately 280 members..

In February of 1997, we merged with a part of Local Lodge 987, of the I.A.M.A.W., which was being disbanded, and acquired ten new Bargaining Units. In 1997 the Security Guards at G. E. Hydro, members of Local Lodge 2235, of the I.A.M.A.W., voted to transfer to Local Lodge 1660, and in November of 1997 the last remaining Bargaining Unit of Local Lodge 1530, of the I.A.M.A.W., which had relocated from Sherbrooke, Quebec to Hull, Quebec, merged with us.

Presently, we represent members of 15 Bargaining Units in 15 different companies, with a total of about 450 active members, 165 retirees, (the exact numbers vary from month to month). These units range in size from 4 members up to 225. Since these Bargaining Units have members which earn vastly different salaries, our dues are based on the weighted hourly average of each individual Bargaining Unit.

Local Lodge 1660 had our own Business Agent at one time, but is now affiliated to and serviced by District Lodge 11, which was founded in December of 1996, and we now deal with four different Business Agents. Our Executive Board meetings are held on the first Monday of the month, and our General Assemblies are held on the third Tuesday of the month.
