The Answer is:
Owen Sound, Ontario
Clue #1: Billy Bishop, Canadian World War One Flying Ace, was born and raised here. The Billy Bishop Regional Airport is named after him, and the family home is now the Billy Bishop Home and Museum.
Clue #2 said you can jump in the lake. Owen Sound is the town’s name, but also the name of the Sound itself, a long, narrow inlet bringing the water of Lake Huron (Georgian Bay) right into town. Owen Sound is half on the east side of the Sound, and half on the west, roughly.
Clue #3: The Big Canoe, or Chi-Cheemaun, is the ferry that runs from Tobermory to Manitoulin Island. In the winter, you can see the Chi-Chee tied up in Owen Sound.
Clue #4: Prohibition until 1961. Owen Sound didn’t get a liquor store until 1961, long after Prohibition ended everywhere else. Signs of such temperance are no longer evident. The town has the same ration of beer stores and bars as its peers.
Clue #5: This was a pun! Everyone likes the sound of this place so much they want to own it.
Owen Sound, Ontario, Canada. A beautiful place all year-round.
