Overview:Michael Portillo begins a new journey on the tracks of the Ocean line to explore Canada’s maritime provinces en route to Quebec City. Clutching his 1899 Appleton’s Guide to Canada, he begins in the Atlantic port of Halifax, Nova Scotia, where he discovers an 18th-century British hilltop citadel, manned at the time of his guide by the 78th Highland Regiment. Michael joins the men who recreate the roles of those Scottish soldiers today. At the mercy of the young 'sergeant major', Michael learns the drill in kilt and sporran. Michael follows his Appleton’s to a vast Victorian dry dock, still in use today by shipbuilders for the Royal Canadian Navy and finds out what it takes to build a state-of-the-art Arctic Patrol vessel. He learns of a catastrophic explosion in Halifax harbour in 1917, which killed 2,000 people and left 25,000 homeless. Former residents of an African-Canadian community torn in two by the railway tell Michael of their struggle for redress.
