A kids field trip to a heritage village in Ontario Canada. So, basically some random volunteer.

This page seems to back me up.

The earliest ecclesiastical windows in Ontario are clear – likely English crown glass, such as is found at the Sharon Temple (1825-31) and the Old Stone Church (1840-53) in Thorah, near Beaverton. This glass was safely shipped from England in barrels of molasses, already cut to size. Coloured glass began arriving shortly thereafter. Using materials at hand, early windows were assembled within wood muntins (strips). Examples include the glorious windows in the chapel of Our Lady of the Sacred Heart Convent, Ottawa (1887), designed by Georges Bouillon and re-erected in the National Gallery of Canada in 1988.
