WINDSOR, Ontario—The discovery of two inactive grenades inside a vehicle led to a seven-hour closure of Canada-bound traffic on the Ambassador Bridge at the busiest border closing with the U.S., Windsor police said Tuesday.

The inert grenades were found submerged in an unidentified white powdery substance, police said, leading to the closure from about 9 a.m. to about 4 p.m. Monday.
