A total solar eclipse – when the Moon passes between the Sun and the Earth, completely blocking out the Sun – is a rare occurrence. However, many Canadians will be treated to this once-in-a-lifetime event on Monday, April 8, 2024, which will be visible across North America and dubbed the Great North American Eclipse.
