OTTAWA -- About an hour east of Ottawa is one of the biggest corn mazes you will find in eastern Ontario. This year, seven acres of corn at Ouimet Farms Adventure in Vankleek Hill, Ont. has been carved into a celebration of Disney’s Magic Kingdom. If you walked the full length of all the passages you would travel five kilometers. Owner Andre Ouimet has been doing this for almost a decade. The farm has been in his family for over a century and to keep it running, Ouimet changed his focus from cows and milk to families and fun.
