Phantom Ghost Ship
In Canadian ghostlore, the Ghost Ship of Northumberland Strait is a ghost ship said to sail ablaze within the Northumberland Strait, the body of water that separates Prince Edward Island from Nova Scotia and New Brunswick in eastern Canada.
The ghost ship has become more widely known in recent years in part due to a popular song by Lennie Gallant, a Canadian singer-songwriter from Rustico, Prince Edward Island along with a reference in the podcast Alice Isn't Dead.
