Every single local soccer pitch will be in use this weekend for the Waters Edge Classic.
Spokesman Paul Burke says it's one of the biggest tournaments in the area.
"We have 104 teams coming this year," he says. "That's basically 6,000 people with families, friends and all that coming to Sarnia, so we're using 17 fields."
Teams will compete in boys and girls divisions in U-9 to U-17 age groups.
