Pastor Armstrong is currently the Senior and Founding apostle of Third Day Worship Centre in Kingston, Ontario.

In 1994, God placed a call within Pastor Armstrong’s heart to “Raise the Standard” of God in Canada.  Pastor Armstrong’s heart’s desire is to work and build the Church into a storehouse of power, with the outpourings of the gifts of the Holy Spirit – a weapon and a centre of manifold effectiveness.  His ministry and church are distinguished by the viable manifestations of signs, wonders and healings through means of “Extreme Praise”. 

He is respected as an anointed pastor and an accurate prophet who has been the catalyst to launch an apostolic move in Canada, as well as the United States.
