Sid Carnegie, park manager of the aptly named Shady Maples Trailer Park, was outside the office raking last week when he saw a large maple leaf flutter down and land on the doorstep of the park's office.
"We couldn't believe our eyes," said co-manager Courtney Miehl, who told Carnegie to bring the leaf inside.
"It landed right at my feet," Carnegie said.
"We immediately looked up last year's record and knew that this leaf was a gift from the heavens."
The gargantuan leaf, still wet and not yet opened completely flat, measures 54 centimetres wide and 59.1 centimetres long, including the stem.
Carnegie and Miehl plan to apply to Guinness World Records to have their find assessed. But they already know they've left last year's record holder withering in second place.
Ten-year-old Eve Steel took the record last year with a maple leaf she found last fall in the Cambie Street area of Vancouver that was 44 centimetres wide and 59 centimetres long.
Nine-year-old Joseph Donato of Pickering, Ontario, raked in the title in 2010 with his 34-centimetreby-29-centimetre find.
