Yonker is an unincorporated locality in Senlac Rural Municipality No. 411, Saskatchewan, Canada.[1] It is located about east of Chauvin, Alberta. Yonker is located along the Canadian National Railway (Formerly the Grand Trunk Pacific Railway (GTPR) until 1923). The community gets its name from Mr. O. Winter, who was a contractor for the Grand Trunk Pacific Railway. This line was named alphabetically, from the east, "Vera", after his daughter, "Winter" after himself; and to the west (skipping over 'x') "Yonker", named after his mother's family.
