The Seventh-day Adventist Church in Canada (SDACC) is organized as a constituent entity of the North American Division of Seventh-day Adventists (SDA). The Adventist presence in Canada dates back to the early and mid-1800s and the Millerite movement. William Miller, Joshua Himes, and Josiah Litch all helped build the Millerite cause on Canadian soil. The Seventh-day Adventist Church became an organized Canadian entity in the late 1870s starting in Quebec. By the first decade of the 1900s, the church had its roots down all across the continent. Today, all of Canada and the French possessions of St. Pierre and Miquelon comprise the official territory of the Seventh-day Adventist Church in Canada. Its administrative units are the British Columbia, Alberta, Manitoba-Saskatchewan, Ontario, Quebec, and Maritime Conferences and the Seventh-day Adventist Church in Newfoundland and Labrador. The 2018 Seventh-day Adventist Yearbook lists 388 churches and a membership of 71,376. Adventist enterprises include worship services in local congregations, annual regional "camp meetings", children's summer camps, a world session every five years, the publishing of tracts and journals, broadcast media, evangelistic meetings, and the operation of schools, medical facilities, and humanitarian enterprises.

This led him to the Eastern Townships of Quebec. Miller, Joshua Himes, and Josiah Litch all visited Canada. Miller's sister lived in the Eastern Townships of Quebec. Josiah Litch lived in that district and led in Millerite activities there. Canada became an integral part of their activities. The interest in Miller's teachings was extensive in the Canadas and the Maritimes. Under the leadership of Josiah Litch, the first Millerite camp meeting took place in Canada, at Hatley, Quebec. Sabbatarian Adventists After the disappointment of October 22, 1844, Millerites developed into several divergent groups. The Sabbatarian group led by the Whites, Joseph Bates and others sought out the scattered Millerites and presented their Sabbath understanding to them. In the early 1850s Joseph Bates and Hiram Edson traveled along the northern shore of Lake Ontario trudging through knee-deep snow seeking out the Millerites. Thirty years later, the Adventist presence in Canada was still in its nascent stage. The first Seventh-day Adventist church in Canada was at South Stukely, Quebec. It organized on September 30, 1877, with 16 members. The Canada Conference, made up of members from both Ontario
