AMPCO is the voice of industrial power users in Ontario 

Our objective is industrial electricity rates that are competitive, fair and efficient

Ontario’s electricity system is dynamic, with multiple agencies and many moving parts. It can seem very complicated. AMPCO serves its members with critical analysis of electricity policy and regulation, market research and analysis, and expert representation on the policy and regulatory matters that affect members' bottom line.

We provide clear communications and effective advocacy.

We are the forum of choice for major power consumers who recognize that their business success - and Ontario's manufacturing economy - depends on electricity policy and regulation that promotes efficiency and protects the interests of consumers.
