Worship at Holy Trinity, Thornhill, is key to parish life. The Participation of the members is evident in almost every aspect of our worship life, as lay readers, lectors and leaders of the Prayers of the people, chalice bearers, servers, acolytes  and choir members.  There are two services using The Book of Alternative Services every Sunday at 8:00 a.m. (said Eucharist) and 10:00 a.m. (sung Eucharist). As well, a said Eucharist using the BAS is offered midweek.  Healing is a part of the 10:00 a.m. service on the third Sunday  of the month.

Morning Prayer from The Book of Common Prayer is offered on fifth Sundays.

Throughout the year there are special services during Advent, Lent, Holy Week, Easter and some feast days, e.g. the Baptism of Our Lord, Pentecost and All Saints Day. A Lessons and Carols service is held during Advent. Christmas is celebrated with Eucharist services on Christmas Eve as well as Christmas Day. Holy Week is marked with Palm Sunday, Maundy Thursday and Good Friday services. As well other special days are celebrated such as Thanksgiving and Remembrance Day.

As a part of our outreach work our clergy conduct a service at Glynnwood Retirement Residence on the third Thursday of each month and our lay readers lead a Sunday worship service at York Central Hospital on a scheduled basis.

There are several veterans who have served our country on the battlefield. We honour them and all veterans with a special celebration on Remembrance Day.


The Holy Eucharist (Holy Communion, Mass, or the Lord's Supper), is the means by which Christ becomes present to the Christian community gathered in his name. This sacrament was instituted by Jesus on the night before he died. It was commanded by Christ for the continual remembrance of his life, death and resurrection

The celebration of the eucharist is the work of the whole People of God. It is the central act of gathered worship, renewing the Body of Christ as the Church through the reception of the Body of Christ as the Blessed Sacrament, his spiritual body and blood. The matter consists of bread and wine.

In this sacrament, Christ is both encountered and incorporated. As such, the Eucharistic action looks backward as a memorial of Christ's sacrifice, forward as a foretaste of the heavenly banquet, and to the present as an Incarnation of Christ in the lives of the community and of individual believers.

In 1995, the International Anglican Liturgical Consultation involving liturgical scholars from over half the Provinces of the Anglican Communion unanimously agreed that “the fundamental character of the eucharistic prayer is thanksgiving, and the whole eucharistic prayer should be seen as consecratory. The elements of memorial and invocation are caught up within the movement of thanksgiving”
