Communications, Energy and Paperworkers Union of Canada (CEP; French: Syndicat canadien des communications, de l'énergie et du papier [SCEP]) was a largely private-sector labour union with 150,000 members, active from 1992 to 2013.

The communications portion of CEP consisted of workers from telecommunications (principally Bell Canada), private TV stations, newspapers, commercial print and new media (such as Internet and web design).

[citation needed] In 2005 nearly all Canadian members of the American-based Graphic Communications International Union (GCIU) representing newspaper press operators and commercial print workers joined CEP, though GCIU members in Quebec joined Teamsters Canada.

[2] The energy portion of CEP consisted mainly of Canadian workers in the oil, gas and chemical sectors, while the paperworkers portion of CEP consisted of pulp and paper workers in the Maritimes, Quebec, Ontario, Alberta and British Columbia.

After the strike any worker who left the CUOE to work at other Ontario Hydro plant lost his seniority.

Small groups of engineers employed mainly in district heating and at hospitals tried to maintain and regain membership for the next 20 years.

The stationary engineers faced technological change and continued opposition from employers who feared a broader union of workers in this critical area.

Larger unions in the public sector and industry often would base wage settlements and pay equity on the stationary engineer position in workplaces because if this group were to join a strike, it would be difficult to keep a facility in operation.

There was also attempts by many companies and professionals to eliminate stationary engineer positions using technology and equipment like coil tube boilers.
