Motto : 

"Per majores gratiam"

Meaning : Thanks to our ancestors

In Old French :

"D'azur à bande de gueule accompagné d'une ancre de sable en chef et de trois épis d'or en pointe."

In English :

"A blue background crossed with a diagonal red stripe running from the bottom left, accompanied by three golden ears of wheat in the lower left corner and a black anchor in the upper right corner."

Meaning

The symbols

The anchor represents the voyage of our ancestors who crossed the Atlantic ocean by boat, during an era in which navigation was, to say the least, perilous, and who dropped permanent anchor in New-France.

The three ears of wheat symbolize farming, the occupation of  the great majority of our ancestors up until the beginning of the 20th century. The three ears represent the first three Gareaus (Jean, Pierre and Marie Gareau dit Saintonge) who, around 1667, were the original stock in New-France.

The colours

The Bleu represents the French origins of the great majority of our ancestors. It equally depicts heaven, which gathered these  profoundly Christian ancestors.

The Red represents the integration of many Gareau families into the english culture (Canadian or American).

The Gold of the wheat symbolizes the moral richness of our ancestors

The Black of the anchor symbolizes the difficulties that the first colonists had to face in this territory disputed by the natives (Amerindians).
