Executives with the International Children's Games say they are impressed by Windsor so far, as the events are about to begin.
Richard Smith, secretary general of the ICG, says the new aquatic centre, with its 50-metre pool, stands out.
"I'm going to be very happy that the city of Windsor is going to be having a legacy of the ICG. We're the first ones to be using it. This will allow you to bring in major world swim events," he said.
The opening ceremony is planned for Thursday night at the WFCU Centre. More than 7,000 people are expected.
The executive committee for the games is pleased with how ready Windsor is to host the event.
Smith said he is impressed by the 1,200 volunteers.
"This team has a humongous experience on doing international and high-level sports, you can tell that," Smith said. "I have experience of working with over 10 games and I know within two or three sentences if somebody knows what they're talking about or if they're snowballing you. We feel very in place here."
The games run until Sunday night, with a closing ceremony at the Riverfront Festival Plaza.
Some of the sports competitions, including baseball and tennis, begin early Thursday.
