Investigator Use
Canada411 (canada411.ca) is Canada's official telephone directory service providing name, address, and phone number lookup capabilities for Canadian individuals and businesses. Operated by Yellow Pages Group, it aggregates telecommunications directory listings across Canadian provinces and territories.
For OSINT investigators working cases with Canadian subjects, Canada411 is the primary reference for Canadian telephone and address lookup. When a suspect, witness, or subject of interest is Canadian, Canada411 provides contact information drawn from official directory listings — more reliable than general people search aggregators for Canadian data.
Reverse phone lookup through Canada411 allows investigators to identify the registered name and address associated with a Canadian phone number, subject to listing status. Listed residential and business numbers return the registered subscriber information, which may provide identity and address intelligence.
Address lookup provides a people-search function — searching by name and city or province returns matching directory listings, providing verified contact information for individuals who appear in official Canadian telephone directories.
For business investigations in Canada, Canada411's business directory provides company names, addresses, phone numbers, and basic business category information that can be used to verify business registrations, identify business contacts, and establish physical locations.
Canada411's coverage reflects voluntary opt-in telephone directory listings — individuals who have opted out of directory listings or use unlisted numbers will not appear, and cell phone numbers are generally not included in traditional directory listings.
For comprehensive Canadian people investigation, Canada411 should be combined with provincial property registry searches, Canadian corporation databases (SEDAR, provincial registries), and Canadian court record searches for complete subject coverage.
