A strong earthquake struck southern Canada, generating seismic waves that were felt across multiple states in the United States and affecting millions of people in both countries.

The earthquake's epicenter was located in southern Canada, though specific magnitude and depth details were not immediately available from initial reports. The tremor was significant enough to be detected across international borders.

Residents across several US states reported feeling the earthquake, indicating the substantial reach of the seismic activity. The widespread nature of the felt reports suggests the earthquake was of considerable magnitude.

Millions of people experienced the shaking, though immediate reports of damage or injuries were not specified in initial accounts. Emergency services and geological monitoring agencies are likely assessing the full impact of the seismic event.

Earthquakes originating in Canada that are felt across multiple US states are relatively uncommon occurrences that typically indicate significant seismic activity in the region.
