Throughout the late 1920's, Trinity United Church was thriving, until hardship times hit with the onset of the Great Depression.  The Depression severely affected the Town of Capreol with many workers being laid off or forced to relocate.  The hardships were experienced in the church as well and spending for church projects was cut to an absolute minimum.  When the Imperial Theatre closed, Reverend Lyttle, who had once worked as a projectionist, purchased a movie projector, obtained some films, and turned the basement of the church into a movie house.  This helped to bring in additional revenues for the parish during some of the difficult years.

When Reverend Lyttle departed for his new ministry in Scarborough, Ontario in 1932, he was met at the train platform by a large crowd of well-wishers from every religious denomination in Capreol.

Throughout the 1930's, Trinity United would put on stage productions at the old Capreol Community Centre to raise money to pay off the debt still owing on the church.

During the war years, eighty men and nine women from Trinity United Church joined the armed forces.  Of these, seven did not return.  The names of all of the enlistees were recorded on three scrolls (prepared by Mr. Chester R. Judd) which are located in the upper vestibule of the church.

With the great shortage of ministers available to congregations, Trinity United was fortunate to retain its minister during the war.
