An estimated one million people will line both sides of the Detroit River to watch the massive Target Fireworks display.
Windsor Police Chief Al Frederick says that many people presents a challenge.
"On an annual basis,it's our biggest night of deployment," he said. "There is no special time off, everyone is here and they're working.
"Not only that we have a full compliment of our 85 auxiliary officers also working.
"On a typical day, we get about 200 calls for service, last year we had over 400 911 calls for service on fireworks night."
The chief says a no-alcohol bylaw is in effect and will be enforced which includes searching coolers and backpacks.
Road closures will happen along the river. While they may be a headache, Frederick says they work perfectly.
"Twenty years ago it was 2 a.m. before all the traffic left the downtown core, now it's before midnight," Frederick said. "They really have done a good job working with the city, city buses and that sort of thing, that's the biggest challenge, is moving the people in and out safely. "
