The purpose
Officiant:
Welcome family, friends and loved ones. We gather here today to celebrate the marriage of Applicant and Applicant. You have come here to share in this formal commitment they make to one another, to offer your love and support to this union, and to allow Applicant and Applicant to start their married life together surrounded by the people dearest and most important to them.
Marriage is the faithful union between two people, the result of which is the growth of a family whose members support and enjoy each other in good times and in bad times. Marriage is not to be entered upon thoughtlessly or irresponsibly but rather with maturity and honesty.
Therefore, if there is anyone present who can show just cause why these two persons may not be lawfully joined together in matrimony, they should now declare it or hereafter remain silent.
Officiant to each participant in turn:
I do solemnly declare that I do not know of any lawful impediment why I, Applicant, may not be joined in matrimony to Applicant.
Declaration of Intent and Vows
Officiant to each participant in turns:
Would you please face each other and join hands.
Please repeat after me:
I call upon these persons here present, to witness that I Applicant do take you Applicant to be my lawful wedded (wife/husband/spouse/partner). To laugh with you in joy, to grieve with you in sorrow, to encourage you in doubt, to grow with you in love, and to be faithful to you alone, as long as we both shall live.
*Personal vows exchanged here if applicable
Exchange of Rings
*Rings exchanged here if applicable
Officiant to each participant in turn:
These rings are a symbol of your love and life together. Every time you look at them may you be reminded of the commitment that you have made to each other today.
Please place the ring on Applicant's finger, hold it there and say the words to him/her/them:
I give you this ring as a symbol of my love and lifelong faithfulness to you. With this ring, I thee wed.
Pronouncement
Officiant:
Applicant and Applicant have pledged themselves to each other and have declared this symbolically by their vows and exchange of rings.
I, Officiant, by virtue of the powers vested in me by the Marriage Act of Ontario, do hereby pronounce you Applicant and Applicant to be (husband and wife/partners in life/married).
You may celebrate your marriage with a kiss.
Service Conclusion
Officiant:
May you enjoy length of days, fulfillment of hopes and peace and contentment of mind as you day by day live and fulfill the terms of this covenant you have made with one another. I wish you happiness and prosperity and may the vows you made to each other today, sustain you forever.
