In Canada, "two pieces of ID" usually refers to a combination of a "Primary" and a "Secondary" document to verify identity for government services, banking, or employment. A primary ID is typically a government-issued photo document, such as a Canadian Passport, a Provincial Driver’s License, or a Permanent Resident Card. These documents confirm both your identity and your legal status or residency. A secondary ID is often used to support the primary one and may not necessarily have a photo; common examples include a Certificate of Canadian Citizenship, a Social Insurance Number (SIN) card (though many are now digital), a provincial health card (acceptance varies by province), or even a major credit card or birth certificate. For high-security transactions, like opening a bank account, many institutions require at least one piece of government-issued photo ID. The specific requirements can vary slightly depending on whether you are dealing with federal or provincial authorities.
