As with every Canadian municipality, Sudbury, Ontario has a free 411 service that's available for use in three different ways. Residents aren't expected to pay for 411 anywhere in Canada.
Sudbury's 411 is available over the phone by simply dialling 411. The only fees associated with a 411 call are if the operator connects you to the number you are trying to find. Alternatively, you can access 411 online through Canada411, the official phone book, or through 411.ca, a third-party site similar to Canada 411. Finally, Sudbury residents receive a local 411 white pages phone book at regular intervals through the mail.
