Canada will this week get a glimpse of what women's boxing will look like when it makes its Olympic debut at the London Games this summer.

Some 65 boxers from 15 countries – many of them Olympic medal contenders – will fight in Cornwall, Ont., starting Wednesday at the American Boxing Confederation Women's Elite Continental Championships.

It is a tune-up for next month's women's world boxing championships in Qinhuangdao, China – the only qualifying event for the 2012 Olympics, which will give berths to the top eight fighters from the three Olympic weight classes (51 kilograms, 60 kg, 75 kg).
