Formerly C.A.W. and U.E., we have a proud history of being

the first U.E. charter formed in Canada, chartered in 1937...

Welcome to Unifor Local 504! Unifor was officially formed on August 31, 2013 at a Founding Convention in Toronto, Ontario.

It marked the coming together of the Canadian Auto Workers Union (CAW) and the Communications, Energy and Paperworkers Union of Canada (CEP) --

two of Canada's largest and most influential labour unions. Unifor is now Canada's largest private sector union, with more than 300,000 members across the country, working in every major sector of the Canadian economy.

See below previous history of CAW Local 504, and how it came to be the proud union it is today.


Local 504 is comprised of Gaming, Healthcare,

Foundries, Warehousing, Auto Part Manufacturing

and Industrial Manufacturing members.
