Buying unlocked gives you the freedom to switch carriers, use a local SIM while travelling, and avoid being tied to a contract you no longer want. Canadian carrier rules have required phones to ship unlocked by default for several years, but plenty of used and discounted phones in circulation are still carrier-locked, so it is worth knowing what to check before buying.
Band compatibility is the part people skip and later regret. A phone built primarily for the US market can miss specific bands used by Canadian regional carriers, which shows up as weak signal or no 5G in areas where your current phone works fine. Always check the exact model number against your carrier's supported bands, not just the country the phone was sold in.
This guide covers what unlocked actually means in Canada today, when importing a US phone makes financial sense, and which unlocked phones are worth buying at each price point.
