Johnny MacDonald was born in Christmas Island, Cape Breton County, to Dan Angus MacDonald of Ottawa Brook and Margaret (MacNeil) of Christmas Island. In the mid to late 1930s, when Johnny was still a child, his family moved to Ottawa Brook, Victoria County. His father, Dan Angus, acquired land there from his own father, Donald. Together, Dan Angus and Margaret built a home on the property and raised their family. During this time, Dan Angus also served as the lighthouse keeper in Ottawa Brook.

As an adult, Johnny lived with his brother, Dan James, in a home located just a few hundred feet from the railway tracks and station. Both brothers worked for CNR and were also skilled fishermen. They would jig cod in the harbour using spooled lines and large lead jigs, hauling in fish one at a time. The brothers estimated their largest cod catch to weigh around 50 pounds. At the shore, they set up a table for cutting and cleaning the fish, and Johnny would often shuck and eat raw oysters straight from the shell to amuse—or startle—his nieces and nephews. They also laid out racks of dried salted cod on the hillside near their home.

In addition to fishing cod, oysters, and occasionally eels, the brothers engaged in small-scale farming during their younger years. Each spring, they planted potatoes, ploughing the fields with a team of horses.

Johnny had a deep love for his Gaelic language and culture. He often spent hours in the kitchen of the old family home, speaking Gaelic with visitors. His conversations with his neighbour, Jimmy “Section” MacDonald, were particularly lively and filled with laughter. When asked to translate their jokes into English, the two men would exchange knowing smiles, remark that it "wouldn’t make any sense," and continue their spirited Gaelic exchange.Johnny passed away in 1985 and is buried in Sacred Heart Cemetery, MacKinnon’s Harbour.
