What year did residential schools introduce summer holidays?

Residential schools in Canada began to introduce summer holidays in the late 19th and early 20th centuries, with some schools adopting this practice as early as the 1870s. The length of the summer break varied among different schools and would typically last from a few weeks to a couple of months. However, these holidays were often used by the schools as opportunities for students to engage in farm work or other forms of manual labor.
