Come for a visit, we are looking forward to see you. UNDERSTAND MORE


The Unitarian Congregation in Mississauga is a religious community of individuals who are guided by compassion, reason and love on an individual search for truth and meaning. We are a growing and diverse congregation. We find meaning and value in the rich and deep history of Unitarianism because our religious tradition draws inspiration from many sources including the wisdom of the world’s faith traditions, nature, science, and contemporary thought.

Unitarians have a message of acceptance to share worldwide. Born from a belief in freedom of religious thought, Unitarians come together in to live our principles and to build a better, more peaceful, world. Our community in Mississauga is welcoming to all, and respects and celebrates all diverse identities.


Ministry in the Unitarian Universalist tradition has four elements: to be a messenger of wonder, reminding us that we all are part of the greater whole; to be a facilitator of community, helping us to develop healthy systems; to be a witness to the ups and downs of our lives; and to be a catalyst for change, in ourselves and in society.

The Unitarian Congregation in Mississauga is served by Reverend Fiona Heath. Rev. Fiona believes Unitarian Universalism has a message worth sharing, one that challenges us to live by our principles, nourished by our connections to the earth.

Fiona can be contacted at  minister@uucm.ca.  Fiona’s personal blog can be found at emptychalice.com.

While Rev. Fiona is the spiritual leader of this chalice community, ministry is more than the work of the minister. As Unitarian Universalists we support shared ministry, members also offer ministry to each other and the wider world through caring for one another, working towards a better society, and participating in services.

From October to May we seek to deepen in spirit by focusing on a theme, explored through on-line resources, spiritual exercises, thought provoking questions, services and in small groups.  On the third Sunday of the month, we have a drop-in theme group, for anyone who would like to share their experiences.

Themes like sanctuary, resistance, and balance have been the catalyst not just for insightful discussions but for transforming ourselves, providing the starter for living with greater integrity and purpose.  

We will post resources on-line here on the website, and a limited number of paper copies will also be available in the foyer.

Acceptance of one another and encouragement to spiritual growth


SourceFire Logo

SourceFire is the Neo-Pagan circle of The Unitarian Congregation in Mississauga.  We impose no dogma and encourage a free and responsible search for truth intersecting with the Seven Principles and the Six Sources – specifically the Sixth Source –  of Unitarianism with which we find no conflict.  We are inspired by the Re-claiming Tradition as established by Starhawk and the work of the Covenant of Unitarian Universalist Pagans (CUUPS).  We function under the Worship Committee of UCM, and as such are bound by the policies and philosophies of the Congregation.

SourceFire marks the high points on the Wheel of the Year with rituals and sometimes special services at UCM where we celebrate and honour the Earth.  Rituals and services can include an invocation, casting a circle, calling the Directions, meditation, dance, drumming, and singing.

SourceFire is co-facilitated by SourceFire’s founder Cassie Rawlinson, and Ellen Newman.  They and a small group of ritual leaders co-create each ritual and service.  Those interested in becoming ritual leaders are required to take the SourceFire Ritual Leader Training which is offered each November and/or reach out to the co-facilitators for a consultation.  Please contact them if you have any questions:  Cassie Rawlinson – cassie.rawlinson@gmail.com or Ellen Newman – hekate1618@gmail.com.  Please see below for our ritual dates.  Blessed Be!


The Unitarian Congregation in Mississauga has experienced Lay Chaplains who are licensed under the Marriage Act of Ontario, serving the Peel and Halton Regions and surrounding areas. Fees for ceremonies are discussed in advance with the Lay Chaplain. Our Lay Chaplains lead various Rites of Passage for the general public in the area, in many different locations such as private homes, public or home gardens and rented halls. Preparations for services are in consultation with the parties involved.

What else do lay chaplains do? Lay chaplains also officiate at weddings, child dedications, memorial services, house blessings, coming out celebrations, coming of age rituals, and other milestone ceremonies. Lay Chaplains craft a custom service for you which is reflective of your personal circumstances and beliefs. In each case, they work with the individuals involved to create a ceremony that is rich in metaphor and meaning, drawing upon the religious or other values of the people who have come to them for support.

Who trains lay chaplains? Unitarian lay chaplains are licensed through the CUC, by their respective provinces, to legally solemnize weddings. The CUC provides the training for new lay chaplains and The National CUC Lay Chaplaincy Committee oversees the program. There are nearly 60 lay chaplains across Canada (an average of two for every congregation). The program is foremost one of ensuring the “right to a rite” for anyone – Unitarian or not, who wants a religious ceremony including multicultural or mixed faith ceremonies, custom designed for them to mark a significant passage in their individual or family life. What about same-sex weddings? Unitarians have led the way, literally for decades, on same-sex unions and marriages. In 1974, the Rev. Norm Naylor, a Unitarian Universalist minister in Winnipeg, officiated at the first same-sex marriage performed in Canada. In the intervening years, lay chaplains performed hundreds of “services of union” even though they weren’t legally recognized by the provinces. At the national level, the CUC was part of the lobbying effort that led to the legalization of equal marriage in 2005. Today our lay chaplains perform marriages in every part of Canada regardless of gender expression and sexual orientation.
