We want to hear from you…
Hundreds of thousands of Ontarians contact us every year: you want to participate in a program, make a comment or ask a question, or complain about the way we are dealing with something that affects you.

We try very hard to follow the three “R”s of customer service — Responsive. Reliable. Respectful — when we are responding to your needs.
