An earthquake felt from Ottawa to Montreal rattled pictures off walls, but caused no significant damage.
Natural Resources Canada reports that a magnitude 3.8 earthquake centred near near Rigaud, Que., occurred at 6 p.m. on Wednesday evening.
John Stalker was in his cottage when he heard a loud rumble.
"All of a sudden it sounded like a jet landed on me, or something exploded in the garage," Stalker told CTV Ottawa.
"I came out just to make sure my garage hadn't gone up in flames or something like that, and about two minutes later my neighbour came over and said, 'Did you feel that?'"
Patrons and employees at a restaurant in Hawkesbury, Ont., were also startled when shaking began.
"I just felt a huge boom and I thought somebody fell down or something," said Liam Dias, an employee at the Stephanie's Grill and Bar. "All the glasses were shaking upstairs."
But beyond a bit of vibration, Natural Resources Canada says, "There are no reports of damage, and none would be expected."
