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.   


For the first two years of theme ministry materials (September 2015 – May 2017), check out the archives  at the previous website.

As G.K. Chesterton said, “There’s a lot of difference between listening and hearing.” This month we explore the change that can happen when we take time to truly listen to each other – including those we find it hardest to hear.  Read more.

Our second principle is to seek “justice, equity and compassion for all people.”  Seeking equity makes the world more fair for more people.  What is our work to do, to help UCM be a more equitable community?  Read more.

All of us, in some way or another, at some time or another, long to belong. No one likes leaning against the closed door listening to everyone laughing inside.  Humans need a place where we belong – be accepted as we are.  What can we do to open the door and welcome others in?  Read more.

We are “always en route to integrity”, attempting to bring our choices and behaviours in alignment with our character.  Integrity isn’t something we achieve, but something we practice over and over again as we learn to take responsibility for all we do in the world.  Read more.

Sometimes resistance involves struggle and requires us to disobey; other times it asks us to be ourselves and not hide our truth.  Sometimes it involves defeating an enemy;  other times it is realizing that treating others as the enemy defeats us all.  Read more.

What is wisdom in an age of endless information and dis-information? Wisdom isn’t simply knowledge, but an ability to understand and discern meaning – knowing what matters. Wisdom takes a moral stance.  Read more.

To be liberated is to be free. To find freedom from oppression, discrimination, consumerism, fear, and more. To be free to be our authentic self. What does it mean to be a people of liberation?  Read more.

To find joy in the world is to face the hard and painful truths of living, and say, “Yes, and…”.    Experiencing joy is restorative – it connects us to the wondrous beauty of all that is.  Joy is a power that gets easily dismissed but it is vital to living well.  Read more.

Please note that SourceFire is on hiatus during 2018-19.

SourceFire is the 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 of Unitarianism with which we find no conflict.

We are a diverse and multi-generational group that provides a community and place of worship for area Pagans and Pagan families.

The high points on the wheel of the year are marked with special rituals as well as services at UCM We celebrate and honour the earth and the Wheel of the Year with meditation, dance, drumming, singing and ritual. We have an Administration Council that helps small groups take turns crafting each meeting by sharing their talents and experiences.

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 its Lay Chaplaincy Program Steering Committee oversees the program. There are nearly 90 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.
