Manresa Jesuit Spiritual Renewal Centre, Spiritual retreat center in Pickering, Canada

The Manresa Jesuit Spiritual Renewal Centre occupies a former 100-acre farm in north Pickering, Ontario, next to Pine Ridge Secondary School off Finch Avenue. Its buildings include the Retreat House, where guests are accommodated, and the 1912 Manor House, where meals are prepared. A St. Ignatius Chapel and prayer centre were added in the 1990s.

Lay Ignatian retreats began in 1924 after a newspaper advert, and in September 1925 thirteen men made a retreat at St. Augustine's Seminary in Toronto, organised by Senator Frank O'Connor with Fr. John M. Filion SJ and Fr. Joseph Fallon SJ as directors. Fr. James Fleming SJ opened the first Manresa centre in Erindale in November 1946 with room for eighteen retreatants; it soon moved to Pickering, where retreats continued days later.

Retreats follow the Spiritual Exercises of Ignatius of Loyola, the Jesuit founder who spent a year in solitude at Manresa in Spain, after which the centre is named. The first lay retreat organised by Senator Frank O'Connor and directed by Fr. John M. Filion SJ and Fr. Joseph Fallon SJ drew thirteen men to St. Augustine's Seminary in Toronto in September 1925. Members of the Sodality of Our Lady of the Way, later the Christian Life Community, made retreats at Regis College.

The centre sits in north Pickering just off Finch Avenue, next to Pine Ridge Secondary School, with the La Storta community house and the Rene Goupil House retirement community as neighbours. Meals are served in the Manor House, while overnight retreatants stay in the Retreat House. Retreats follow the Spiritual Exercises of Ignatius of Loyola, and each retreatant gives an offering according to means rather than a fixed fee.

The Manor House was built in the summer of 1912 by Lord Hyde alone, George Villiers, later sixth Earl of Clarendon and Governor-General of the Union of South Africa; Lord Somers, Arthur Somers-Cocks, shared the Clarendon Wood estate but not the construction. During the building work the two lords showed the property to Prince Arthur, Duke of Connaught, son of Queen Victoria, and his family.
