It looks like Canada may need to up its border security.
An estimated 1,500 Americans illegally washed ashore in Canada Sunday afternoon after strong winds blew their floats and inner tubes across the St. Clair River, according to CBC News.
The Americans were participating in the annual Port Huron Float Down in Port Huron, Michigan, when high winds pushed them to different points along the Canadian shore.
There were people in places you'd never think something would float, but there were Americans everywhere.
Garapick told CBC News that winds were between 10 and 15 knots.
"The people who take part in this are not mariners," Garapick told CBC News. "They don't look at the wind, the weather and the waves. We knew from the get-go, the winds were going to cause a problem."
After the floaters were fished out of the water, they were shipped back across the border on Sarnia Transit buses.
YouTube user Ernie Jacobs posted a video of his group being "towed back to the U.S."
Garapick told CBC News many of the Americans were terrified because they entered Canada without any form of identification and many were drinking alcohol.
Some even attempted to swim back to the U.S., but were stopped by the Canadian Coast Guard.
The last bus full of Americans left Sarnia, Ontario, around 7 p.m. Sunday.
