Fireworks are set to light up the sky at Ashbridge's Bay Park on Monday evening in celebration of Victoria Day.

The fireworks display will be lit from a designated area that will make the show visible to crowds on the boardwalk below, from Coxwell Avenue to Victoria Park.

The fireworks display is scheduled to begin at 9:45 p.m. and will last about 15-20 minutes.

Over 2,000 fireworks will be lit in that time, with the largest measuring up to 12 inches (30.5 centimetres).

"The 12-inch (firework) will go 1,200 feet in the air and then explode in a huge break," said David Whysall, who designed and choreographed the show.

He said that the 14-minute show took close to 14 hours to set up. Whysall's crew is also responsible for detonating the fireworks on Monday evening.

He said there were more crew members needed than usual this year due to the long weekend's unsettled weather.

Although Whysall said he doesn't want to see a lightening storm before the show, the show will continue rain or shine.

Whysall has been in the fireworks business since 1965 and said that recent changes have included new colours to fireworks and computerized detonations.

He wouldn't say the exact cost of putting on the Victoria Day show, but said it was comparable to buying a car.

"It's not cheap, there are lots of zeros," he said.

As many as 80,000 people are expected to attend the fireworks display, and officials are asking commuters to consider taking public transit as nearby roads will become congested.

Heavy traffic has closed Lakeshore Boulevard, between Leslie Street and Woodbine Avenue in previous years.
