With its graceful spire and 37 stained glass windows, Our Lady of Mercy Church is one of Sarnia’s most historic landmarks. Among its more notable features, is its yellow bricks which were produced in local brickyards dating back to the 1860s. RTM was honoured to be able to undertake its heritage restoration, including the church’s masonry, lead-coated copper cladding, wood windows, and its iconic steeple.
