Canada's largest candy company celebrates a century of chocolate-making on Friday by handing outthousands ofchocolate bars for free.

The Cadbury Adams chocolate factory, located in a residential neighbourhood in downtown Toronto, is one of the city's few inner-city factories.

"Our Factory has been a vibrant part of Toronto’s history for more than 100 years. This hidden jewel in the city is where we make all the Cadbury chocolate bars for Canada, some of which are also exported to Europe and Mexico," Lesya Lysyj, Cadbury's senior vice-president,marketing,said in a news release.

When the company first began making chocolate in Toronto in 1906, the bars were produced in bulk and boxed. By 1919, the factory was producing 5.5 million pounds of chocolate annually.

Every year the Cadbury Adams factory, located on Gladstone Avenue between College and Dundas streets, produces close to half a billion chocolate bars, including Cadbury Dairy Milk, Mr. Big, Caramilk and Mini Eggs. The factory is also the birthplace of the Crispy Crunch bar thanks to Harold Oswin, a worker who created the candy bar in 1930 as part of an employee contest.

The chocolate company will be handing out 100,000 free chocolate bars across the country, three-quarters of them in Toronto's Yonge-Dundas Square from 11:30 a.m. to 2 p.m.
