The IRB has expanded the IRB Women's Sevens World Series, adding Canada and England to the series and making it a six-event circuit.

The USA returns with their tournament in Atlanta, Ga. March 14-15 (slightly later in the year than last time), while Rugby Canada's facility, Westhills Stadium, in Langford, BC will host Round 4 April 18-19.

The Twickenham Stoop - somewhat more intimate than the massive Twickenham Stadium, hosts the new English leg in May.

The circuit will finish with a first-ever double-shot, with tournaments on consecutive weekends, in London May 15-16, and Amsterdam May 22-23.

Guangzhou, China is no longer part of the series.

IRB Chairman Bernard Lapasset said: “The level of competition in the Women’s Sevens World Series is at an all-time high, and has been helped by the prospect of taking part in the Olympic Games in Rio in 2016.”

“We now have Canada and London added to the bill for the coming season and given the appetite for quality Rugby and the Sevens Game, I have no doubt that they will be excellent hosts when they welcome the women's series to their shores next year."

12 teams will take part in each round of the IRB Women’s Sevens World Series. Seven teams have qualified as core teams from last season’s series. Hong Kong will host a qualifying competition in September that will see an extra four teams qualify. The 12th team will be invited for each round of the series.
