Historical Summary: The Pine Lake Anglican church originated during the expansion of British settlement in Alberta between the 1890s and World War I.  In the mid-1890s a number of English settlers which included the Alford Brothers, Reg, Bert and Henry, arrived in the Pine Lake.  After their arrival in Alberta, the brothers received periodic gifts from overseas.  One sum of money from their aunts Elizabeth and Henrietta Alford was intended to be "the nucleus of a fund for building a church in your community".  The money was deposited in the Molson's Bank in Calgary and from time to time other sums were added to it by other English settlers in the immediate vicinity of Pine Lake.

Anglican church services were provided in the Pine Lake areas as early as 1895 by a clergyman who attended to the spiritual needs of the people at nine different locations in the area from Bashaw to Olds.  The decision to use the church fund which had been accumulating in the bank was made in 1901.  Construction was undertaken in 1902.  The new church was opened in 1903 by Bishop Pinkham.  One of the elements by which the English settlers recreated something of life in the old country, Holy Trinity Anglican Church stands for the transition of a communion and a community from England to the Canadian prairie west.
