It was formed through the efforts of the late Sir Knight Cec Tufts and Sir Knight Joe Tobin, who felt we should now have our own Assembly in Stratford. Until then the members were affiliated with the Dean Egan Assembly in Seaforth. The assembly was so named in honour of our late and highly esteemed member the Honourable Justice J. Maurice King, Supreme Court Judge, former mayor and alderman of Stratford, former Grand Knight and Past State Deputy of Ontario.

The Justice J. M. King Assembly is what is known as the patriotic wing of the order. Its first Faithful navigator was P.G.K. Al Grant, the Present Navigator is Sir Knight William Verhoeve. The Assembly sponsors a euchre party usually on the last Saturday of the month.
