List of impact craters in Canada

From Wikipedia, the free encyclopedia

This list of impact craters in Canada includes all confirmed impact craters as listed in the Earth Impact Database. These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface features.
