On April 8, 2024, Canada will experience its first total solar eclipse since 1979, but this time, some of the nation's biggest cities will be in or near the path of totality.
The path of totality extends from northwest Mexico, through the U.S., to southeastern Canada. It will be 115 miles (185 kilometers) wide, on average, and only within it will it be possible to experience darkness in the daytime and glimpse the sun's corona with the naked eye for up to 4 minutes, 28 seconds. This path of totality is the moon's umbra, where the moon appears to block the sun's disk completely.
