Cars will make way for more than 90 stalls, business displays, marquees, exhibition areas, entertainment stages, an array of food vendors and children's amusements.

"This will be the first time that The Boulevarde has been closed to vehicle traffic since 2002, when it hosted a village fair," Toronto Chamber of Commerce spokeswoman Brenda Hartmire said.

And it's not just businesses on The Boulevarde who will be displaying their wares.

The Greater Toronto area extends from Teralba to Wangi Wangi, and includes a surprising array of enterprises.

"There are a lot of main street businesses taking part, but since we've been organising this Spring Fair I've discovered a lot of great businesses in our area which I never knew existed," Ms Hartmire said.

Among those are the jewellery designer Nature's Treasures, of Marmong Point; and children's clothing store Frilly Lilly, Jolly Ollie, of Toronto.

Sporting clubs and leisure and community organisations will also have interactive displays.

So visitors to the Spring Fair will get to see a whole lot more than they would on a normal trip into town.

Among the rare treats will be a "mini Antiques Roadshow" in which local experts will assess and offer opinions on hand-held items brought in by patrons.

Another highlight will be the Toronto Home Show, featuring hands-on demonstrations from the team at Lake Timber and Hardware Mitre 10, Toronto, at 1.30pm.

"There really will be something for everyone in the family," Ms Hartmire said.

"And then there's the promotions, giveaways, competitions and, of course, the chance to bag some real bargains and something unusual."

The popular retail strip - from the traffic lights at the intersection with Cary Street, down to the water's edge at the Victory Parade roundabout - will be closed to traffic from 7am to 5pm.

The Spring Fair will run from 10am to 3pm.

A limited number of stalls are available.

PROCEEDS from the Greater Toronto Spring Fair will help Australian farmers in need.

Money will go to the Buy a Bale project, part of the Give Back Campaign Australia.

Farmers are struggling with 70per cent of Queensland drought declared, and 50per cent of NSW also affected,  Brenda Hartmire said.

The Buy a Bale project involves assisting farmers with fodder, water and basic family essentials such as groceries.

Ms Hartmire said a major raffle supporting the Buy a Bale project will be held as part of the Greater Toronto Spring Fair. Local businesses are  being sought to support the raffle through the donation of prizes.
