Organizers of the 107th Royal Manitoba Winter Fair in Brandon, Man., are expecting to see more than 100,000 people at the Keystone Centre for this week's agricultural exhibition.

The annual event, which runs through Saturday, features world-class equestrian shows and cattle shows, about 300 trade show exhibits and hands-on agricultural experiences for visitors — all under one roof.

"This event has so many different moving parts. It's like over a seven-day period, hosting 100 weddings," said Rob O'Connor, general manager of the Provincial Exhibition of Manitoba.

"There's all kinds of different events going on, different people involved."

More than 400 horses are being showcased in the equestrian shows, while the cattle shows feature young beef producers.

O'Connor said the fair is Brandon's biggest event of the year and will bring lots of revenue to the city.

"This event brings about $9 million worth of economic impact [for Brandon] and for the province an additional $4 million, and it brings people from all over the province, all over Canada," he said.
