James Island in British Columbia Available for $75 million

Owned by Telecommunications entrepreneur Craig McCaw, the island was transformed into a resort in the 1980s, having been the site of a Dynamite Plant from the World War II era.

Today it boasts an array of lavish amenities including a private Jack Nicklaus-designed golf course, sandy beaches, an airstrip, a marina, an entertainment centre, a gym and a convenience store.

In terms of accommodation, the island also features a four-bedroom, 5,000-square-foot main residence built from reclaimed cedar, six guest cottages and staff quarters.

Mr McCaw purchased James Island in 1994.
