Sherbourne Blockhouse

Following the Upper Canada Rebellion of 1837 Lieutenant Governor of Upper Canada Sir George Arthur directed the construction of a Sherbourne Blockhouse, and a ring of six other blockhouses -- to guard the approaches to Toronto in case there was another rebellion.

[1][2][3][4] The Sherbourne Blockhouse was located at the northern end of Sherbourne Street, at the current intersection with Bloor, just south of the Rosedale Ravine.

The blockhouses were two stories tall, and designed to accommodate up to 44 soldiers.

[3] The two stories were at 45 degrees to one another—a design intended to make it easier to observe in all directions.

By 1850 they were staffed by a skeleton crew of former soldiers, who served as caretakers.
