Electrical Plug and Power Cord Standards in Canada

Canada follows standardized electrical specifications for plugs, sockets, and power cords to ensure safety and compatibility. Here’s an overview:

1. Voltage and Frequency

• Voltage: 120 volts (V)
• Frequency: 60 Hertz (Hz)**
  This aligns with the North American electrical system, shared with the United States and Mexico.

2. Plug and Socket Types

• Type A (NEMA 1-15):
  • Two flat parallel pins (ungrounded).
  • Commonly used for small appliances and devices without grounding needs.
• Type B (NEMA 5-15):
  • Two flat parallel pins + a round grounding pin (grounded).
  • Standard for most household outlets, especially for larger appliances.

  Canadian outlets accept both Type A and Type B plugs.

3. Power Cord and Outlet Design

• Outlets are designed to accommodate polarized plugs (one pin wider than the other for correct orientation).
• Tamper-resistant outlets (with shutters) are increasingly common in new installations for child safety.

4. Safety Certifications

• All plugs, cords, and devices sold in Canada must meet CSA Group (Canadian Standards Association) standards, often marked as CSA C22.2.
• Recognized certifications also include UL (Underwriters Laboratories) and ETL for compliance with North American safety norms.

5. Compatibility Notes

• Devices from the U.S., Mexico, Japan, and other 120V/60Hz countries are typically compatible.
• Appliances designed for 220–240V systems (e.g., Europe, Asia) require a voltage converter, though many modern electronics (e.g., laptops, phones) support dual voltage (check labels for “100–240V”).
• Travelers from regions using different plug types (e.g., EU Type C, UK Type G) will need a plug adapter.

6. Key Regulations

• The Canadian Electrical Code (CEC) governs installation and safety requirements.
• Extension cords and power bars must include overload protection and meet CSA/UL certifications.

Summary

Canada uses Type A/B plugs at 120V/60Hz, with strict adherence to CSA safety standards. Visitors from outside North America should verify device compatibility and carry adapters/converters as needed. Always check for certification marks on electrical products to ensure compliance.
