Churches The Presbyterians, Methodists and Church of England all held services in the CPR depot beginning in 1883 and townspeople of all denominations attended regardless of affiliation. By 1884 the Presbyterians had built the town's first church and in 1885 the Anglicans the town's second, St Michael and All Angels’. The Methodists built their first church in 1890 and, soon outgrowing it, a second in 1906, the first building being destroyed by fire concurrently with the opening of the new church. The second Methodist church building remains that of the United Church of Canada congregation which came into existence as Grenfell United Church upon the unification of Canadian Presbyterians, Methodists and Congregationalists in 1925, the old Presbyterian church building being sold to the Independent Order of Odd Fellows as a lodge room. It is reported that "[i]n publications of the day, clergy recounted their experiences.

Baker, arriving disappointed to find '... only a handful of people gathered' for a service." The Lutherans built their first Peace Lutheran Church in 1905 and a second, larger building in 1951, the old building being sold to the Ukrainian Orthodox congregation. The Roman Catholics, originally of substantially Irish stock, built St Columbkill Church in 1903 and, with an influx of Polish and Ruthenian families found their numbers considerably increased
