Canada411.ca provides phone number lookup for business and residential landlines in Montreal and the rest of Canada. It also provides reverse phone number lookup, which allows users to find names and addresses using a known phone number.
As with a traditional phone book, Canada411.ca does not provide listings for cellphone numbers or landlines that are unlisted by customer request.
Visitors can find information on requesting or cancelling delivery of their local printed phone directory on the FAQ page of Canada411.ca.
Other websites, such as PeopleByName.com, claim to offer directories of unlisted landline and cellphone numbers. However, as their information is not provided by the telephone companies, it may not be as accurate as that found on Canada411.ca.
