The Township of Wellington North was formed in 1999 with the amalgamation of the Town of Mount Forest, the Village of Arthur, the Townships of West Luther and Arthur, as well some of the outlying areas in the Townships of Peel and West Garafraxa. Stretching over 526 square kilometres, it is now home to over 12,500 people. Wellington North is expected to grow to approximately 20,500 people by 2051 (an increase of more than 64%).
