A plan is in place to handle any Americans or possible asylum seekers who land in Canada during Sunday's Port Huron Float Down.
Sarnia-Lambton MP Marilyn Gladu contacted the Minister of Public Safety and additional resources have been secured.
"We have additional Coast Guard boats, there are also some RCMP [Royal Canadian Mounted Police] folks that are available and extra CBSA [Canada Border Service Agency] folks," says Gladu.
She says they are prepared for any and all events.
"If people come over illegally, they don't have any identification and they claim refugee status... Sarnia is very ill prepared because we don't have a refugee centre like what London has," says Gladu. "We don't have the processing here. So, that's really the contingency that's been put into place is to have the border security agents able to respond and able to call in, as needed, extra resources to process people."
Gladu is really hoping people think about the risks associated with the event.
"Somebody died once doing this. It's a very dangerous activity and I would hope that people would recognize in addition to the taxpayer burden and safety concerns -- people are having to give up their weekends to be on call just incase this unsanctioned event results in something more serious," she says.
Thousands of people are expected to participate in the unsanctioned event which saw hundreds of Americans forced to land in Sarnia in 2016 because of high winds.
The St. Clair River will be closed to all motor vessel traffic between noon and 8pm from just north of the Blue Water Bridge to Stag Island.
Participants are asked to wear lifejackets, carry a passport or NEXUS card, and refrain from drinking alcohol among other things.
