Marylake Augustinian Monastery

[4] An agricultural school was established on the grounds in the 1930s by the Basilian fathers, and in 1942 the Archbishop of Toronto, Cardinal McGuigan, "invited the Augustinians to establish a shrine and to offer a program of weekend retreats for lay people"[2] He expressed that it was his own personal dream that it was his hope that this shrine at the Marylake Centre would become not only an important place of pilgrimage in honour of our Blessed Mother Mary in this area, but that one day it would officially become the centre of Marian devotion for all Ontario.

It is the site for a yearly June pilgrimage by 3,000 Danube Swabians for an open-air mass paying "homage to Germans expelled from Eastern Europe".

[6][7] In October 2012, the Archbishop of Toronto, Cardinal Thomas Christopher Collins, declared Marylake as one of four official archdiocesan sites of sacred pilgrimage for the Year of Faith.

On February 3, 2013, in a Solemn High Mass, the Very Reverend Bernard Scianna, O.S.A., Ph.D., Prior Provincial of the Canadian and Midwest Augustinians, officially blessed and designated the main entrance to the shrine as a holy door open to all who come to Marylake seeking the special graces of the Year of Faith.

After receiving a Marian locution on a retreat in 1974, Harasti made it his quest to build the rosary path at the request of the Blessed Mother Mary.
