It was built in 1865 as a grain storage elevator for the grist mill that once stood alongside it. When the mill was removed in 1942 this building was renovated with the transferred milling equipment and it became the mill and operated as such until the 1960s. It then transferred to a new life as art studio for a local artisan. For me, it still counts as a vator.
(BTW - that's the Rideau Canal in the foreground. Here, grain and flour was shipped - literally.)
