How far ahead must you be able to see if you need to pass another vehicle on a hill or curve in Canada?

In Canada, when passing another vehicle on a hill or curve, you must be able to see at least 150 meters (about 500 feet) ahead. This distance ensures that you have enough visibility to safely complete the maneuver without encountering oncoming traffic. It's crucial to prioritize safety and adhere to local traffic laws when considering passing in these conditions.
