The Rideau Canal locks at Merrickville with three locks have a total lift of twenty five feet. On the south side of the locks there is the old blockhouse, which has been restored by Parks Canada as a tourist site and museum operated by the Merrickville and District Historical Society.
In the last two decades, the region has seen a boom in the local economy mostly related to increased tourism. It is famous for its local crafts people and artists.
William Merrick founded the village of Merrickville in 1794. Attracted to the site by waterpower, he constructed a dam across the river and then built grist, saw and carding mills. It was not long before a community sprang up around the milling activity. In 1821, Merrick built a stone house overlooking his mills.
When the construction crews arrived in 1827 to build the Rideau Canal, the village of Merrick's Mills, as it was then known, was a thriving community of about 300. A plaque was erected by the Merrickville and District Historical Society in remembrance of an unknown number of persons who were buried in the McGuigan Cemetery between the years 1800 and 1900; Many died of pestilence, principally malaria, during the construction of the Rideau Canal.
Unlike most of the pre-canal sites, Merrick's Mills was not destroyed by canal construction. After the canal was completed, the excess water once again turned the wheels of the mills and the improved transportation system caused a surge in commercial activity in the village. By 1851, Merrick's Mills was an impressive industrial centre.
Merrick's Mills continued to thrive into the mid-1860s. The end of the community's industrial growth is closely related to the decline of the commercial phase of the Rideau canal. The rise of the nearby town of Smiths Falls as a major railway hub displaced Merrick's Mills as an industrial leader in the region. Despite the decline, some industry continued in the community. In 1915 a power company was formed at Merrickville to provide electricity for the mills and a foundry, and the woolen mill continued to function until 1954.
The primary source for basic documents (vital statistics, land records, wills) for people who lived in the Province of Ontario is the Archives of Ontario, 134 Ian Macdonald Blvd, Toronto, Ontario, Canada M7A 2C5.
Civil registration did not begin in the province until 1869. Before then there may be church records of baptisms and burials. For the most part these are still held by the denomination who recorded them. Copies of marriage records made pre-1869 had to be sent by individual clergymen to the registrar of the county in which the marriage took place. These marriage records are available through Ontario Archives, on micorfilm through LDS libraries, and on paid and unpaid websites, but because they were copied at the registrars' offices, they cannot be considered a primary source.
Vital Records after 1869
Birth, marriage and death registrations are not open to the public until a specific number of years after the event occurred. Births to 1914 are now available [October 2012]; dates for marriages and deaths are later. Birth and death registration was not universally carried out in the early years after its adoption. Deaths were more apt to be reported than births for several years. The more rural the area, the less likely it would be that these happenings were reported to the authorities.
Land Records and Wills
Information on how to access land records and wills is best sought on the Archives of Ontario website. An ancestor's land holding might be found on Canadian County Atlas Digital Project if he was in occupancy circa 1878.

The original censuses are in the hands of Library and Archives Canada. All of the original census (1851-1911) images are online with the exception of that for 1861. Not all of them are indexed. Later censuses are not yet available. Census divisions were redrawn as the population increased and more land was inhabited.
