Edward Mahon had, like Mackay, arrived in Vancouver in 1888. Mahon began mining operations in the Nelson-Slocan area, naming the camp Castlegar after his ancestral home in Ireland. Returning to Vancouver, he set about purchasing and developing land and businesses on the North Shore, among them Capilano Suspension Bridge.

In 1910, while in Victoria, 48 year old Mahon met and fell in love with Lilette, the 19 year old daughter of his recently deceased friend, James Rebbeck. Mahon's love for Lilette was so great that, in order to see her more often, he arranged for Lilette's mother, Elizabeth D'abbadie Rebbeck, to move to Capilano and manage his bridge property. Mahon's plan worked - he married Lilette a year later!

Elizabeth planted gardens using the rhododendrons, azaleas and hydrangeas that Mahon was importing from the Orient to beautify his other developments. To offer refreshment to the increasing number of visitors, Mahon built the Tea House in 1911, using cedar timbers stacked one on top of the other. Unsure of the bridge's strength, Mahon reinforced it with additional cables in 1914.

The Great War and ensuing years were ones of hardship and loneliness for Elizabeth, until a handsome young forest ranger, 20 years her junior, swept her off her feet! In 1921 "Mac" MacEachran and Elizabeth married. Together Elizabeth and Mac faced the next decade with optimism and energy. Mac was a natural promoter, Elizabeth a gentile hostess. But meagre earnings due to the Depression forced Mac to seek employment elsewhere in the off-season and for several winters he managed warehouses in Tahiti for rum-running friends.

In 1934 Mac announced to Elizabeth that he had a 19 year old daughter, Irene, whom he wished to bring to Capilano. This news devastated Elizabeth, who nevertheless agreed to accept Irene. Arrangements were made to build a new and larger house across the street from the bridge but sadly, Elizabeth died before the house was finished.

Mac then purchased the Bridge from Mahon in 1935 and invited local First Nations to place their totem poles in the park, adding a First Nations theme. In 1945, he sold the bridge to Henri Aubeneau and moved to California.
