Question: What former Canadian MP and Senator named a community in Saskatchewan after a semi-ruined mid-14th-century fortress, located 5 km east of North Berwick, in East Lothian, Scotland?
Context: Tantallon Castle is a semi-ruined mid-14th-century fortress, located 5 km east of North Berwick, in East Lothian, Scotland.  It sits atop a promontory opposite the Bass Rock, looking out onto the Firth of Forth.  The last medieval curtain wall castle to be constructed in Scotland, Tantallon comprises a single wall blocking off the headland, with the other three sides naturally protected by sea cliffs. Drem railway station serves the village of Drem in East Lothian, 5 mi from the seaside town of North Berwick in Scotland.  It is located on the East Coast Main Line (ECML) 18 mi east of Edinburgh Waverley.  Passenger services are provided on the Abellio ScotRail North Berwick Line, and the junction where the North Berwick branch diverges from the ECML is a short distance to the east of the station. North Berwick railway station is a railway station serving the seaside town of North Berwick in East Lothian, Scotland.  It is the terminus of the Edinburgh to North Berwick Line, 22+1/4 mi east of Edinburgh Waverley . The North Berwick witch trials were the trials in 1590 of a number of people from East Lothian, Scotland, accused of witchcraft in the St Andrew's Auld Kirk in North Berwick.  They ran for two years and implicated seventy people.  These included Francis Stewart, 5th Earl of Bothwell on charges of high treason.  The "witches" held their covens on the Auld Kirk Green, part of the modern-day North Berwick Harbour area.  The confessions were extracted by torture in the Old Tolbooth, Edinburgh.  The main source for this story was published in a 1591 pamphlet "Newes from Scotland" and was subsequently published in King James's dissertation on contemporary necromancy titled "Daemonologie" in 1597. The community was founded in 1904 and takes its name from a homestead (which was named "Tantallon" by Scottish Canadian James Moffat Douglas (former Canadian MP and Senator)), who said this part of the Qu'Appelle Valley reminded him of Tantallon Castle in Scotland. John David Home Robertson (born 5 December 1948) is a Labour politician in Scotland.  He was a Member of Parliament (MP) for Berwick and East Lothian and East Lothian from 1978 to 2001 and a Member of the Scottish Parliament (MSP) for East Lothian from 1999 until 2007. The Aberlady, Gullane and North Berwick Railway was promoted independently to develop settlements between Longniddry and North Berwick in East Lothian, Scotland.  It opened its line from a junction near Longniddry as far as Gullane in 1898, but never succeeded in financial terms, and it never competed its line to North Berwick, which already had a branch railway. The North Berwick Branch was a short railway branch line built by the North British Railway to connect North Berwick, in East Lothian, Scotland to its main line.  It was built as a tactical means of excluding competitors from the area, and when it opened in 1850 it was loss making.  The later development of North Berwick as a resort and a golfing centre transformed the branch line. North Berwick ( ; Scottish Gaelic: "Bearaig a Tuath" ) is a seaside town and former royal burgh in East Lothian, Scotland.  It is situated on the south shore of the Firth of Forth, approximately 25 mi north-east of Edinburgh.  North Berwick became a fashionable holiday resort in the nineteenth century because of its two sandy bays, the East (or Milsey) Bay and the West Bay, and continues to attract holidaymakers.  Golf courses at the ends of each bay are open to visitors. The North Berwick Golf Club (NBGC), at North Berwick, East Lothian, was founded in 1832.  It is the 13th oldest golf club in the world and only St Andrews hosts a club which has played continuously over the same course for longer.  Although the NBGC was the first club in the world to allow female members, full membership rights were only granted to ladies in 2005.  The club is based at the North Berwick West Links golf course.
