Canada is celebrating this year's Guinness World Records Day (17 th November) in a big way by challenging record holders to register this season's record breaking Maple Leaves for a chance to make history!

Last year's 2010 Guinness World Records day celebrated pint size Joseph Donato of Ontario whose gargantuan maple leaf discovery led to his inclusion in the Guinness World Records 2012 Edition!

Page 13 of the new edition features Joseph with his leaf at 13.6 inches (34.61cm) wide and 11.5 inches (29.21 cm) long.

The current record sits with the Tanwar family from Richmond, British Columbia who found a 20 inch wide Maple Leaf last December.

Record claims should be submitted directly to together with a signed statement of authentication by a horticulturist and an independent witness of good standing in the community, along with a photograph.

Guidelines will be issued for each record submitted. Records for the largest leaves are assessed on the surface area of the one side of the leaf. If feasible, results will be announced on 17 th November, Canada's Guinness World Records Day.

Guinness World Records Day is an international celebration of record attempts and achievements.

Among other events taking place in Canada, will be a unique attempt in Toronto by Make-A-Wish Canada to create the largest human star!

A Guinness World Records® Official Adjudicator will be on hand to adjudicate the event.
