History
Sainte-Marie Mère de Dieu School came into existence in July 2022 as a result of the joint efforts of Mr. Ubertelli, a group of teachers, parents, and benefactors. Its purpose is to advance Catholic education with a traditional mindset in a rigorous, welcoming, and respectful environment, and to meet the needs of families seeking to educate their children through a thoughtful and conscientious approach. The school has assembled qualified and dedicated teachers who are recognized and experienced, each specialized in their respective fields of expertise. These teachers provide a classical and faithful education. The school has extensive premises in the Saint-François d'Assise church in the Hintonburg area of Ottawa.

Writer and composer by profession, Professor Ubertelli has taught for over twenty years in Ontario and Europe at the secondary and conservatory levels, and has significant experience teaching music, French, history, and philosophy.

A published author, he founded Sainte-Marie School in 2022, partly for his three children. He continues to write and compose alongside managing the school and teaching. For Professor Ubertelli, reason must necessarily be illuminated by faith—a faith informed by history.

Liturgical Calendar
Wednesday, December 17 - Wednesday of Ember Week in AdventEpistle
Book of Isaiah 7,10-15.7,10And the Lord spoke again to Achaz, saying:
7,11Ask thee a sign of the Lord thy God, either unto the depth of hell, or unto the height above.
7,12And Achaz said: I will not ask, and I will not tempt the Lord.
7,13And he said: Hear ye therefore, O house of David: Is it a small thing for you to be grievous to men, that you are grievous to my God also?
7,14Therefore the Lord himself shall give you a sign. Behold a virgin shall conceive, and bear a son and his name shall be called Emmanuel.
7,15He shall eat butter and honey, that he may know to refuse the evil, and to choose the good.
Gospel
Holy Gospel according to Saint Luke 1,26-38.1,26In the sixth month, the angel Gabriel was sent from God into a city of Galilee, called Nazareth,
1,27To a virgin espoused to a man whose name was Joseph, of the house of David: and the virgin's name was Mary.
1,28And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women.
1,29Who having heard, was troubled at his saying and thought with herself what manner of salutation this should be.
1,30And the angel said to her: Fear not, Mary, for thou hast found grace with God.
1,31Behold thou shalt conceive in thy womb and shalt bring forth a son: and thou shalt call his name Jesus.
1,32He shall be great and shall be called the Son of the Most High. And the Lord God shall give unto him the throne of David his father: and he shall reign in the house of Jacob for ever.
1,33And of his kingdom there shall be no end.
1,34And Mary said to the angel: How shall this be done, because I know not man?
1,35And the angel answering, said to her: The Holy Ghost shall come upon thee and the power of the Most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God.
1,36And behold thy cousin Elizabeth, she also hath conceived a son in her old age: and this is the sixth month with her that is called barren.
1,37Because no word shall be impossible with God.
1,38And Mary said: Behold the handmaid of the Lord: be it done to me according to thy word. And the angel departed from her.
