With roots going back to 1936 through the Mouvement des caisses populaires acadiennes, UNI has served New Brunswick's Acadian community for nearly 90 years and has grown to serve members across linguistic lines.
UNI operates under a full-service model, offering chequing accounts, savings products, mortgages, personal loans, business banking, investment products, and insurance. Their mortgage rates are consistently competitive with the major banks and they have local decision-making authority that can benefit borrowers with complex situations.
New Brunswick is Canada's only officially bilingual province, and this creates a distinct banking environment. UNI serves the Francophone Acadian community across NB in both French and English, while English-language credit unions serve primarily English-speaking communities. All major banks offer bilingual service throughout NB, as required by federal and provincial language obligations.
For Francophone New Brunswickers, UNI is often the preferred financial institution because it provides banking in their first language with a deep cultural connection to the Acadian tradition of cooperative economics. The caisse populaire movement was founded on the principle of community self-sufficiency — a principle that remains central to UNI's identity today.
For home buyers in New Brunswick, credit unions — particularly UNI Financial — are a strong option for mortgage financing. Credit union mortgage specialists often understand local property markets better than bank representatives based in larger cities, and their flexibility for self-employed borrowers, seasonal workers, and non-traditional income earners can be valuable in NB's diverse economy.
New Brunswick's 1.0% deed transfer tax on assessed value means buyers already benefit from one of Atlantic Canada's lower transfer tax costs. Pairing this with a competitive credit union mortgage rate can significantly improve the overall economics of buying a New Brunswick home.
Many NB credit union members use KOHO alongside their credit union account. KOHO's no-fee spending account and cash back rewards complement the more traditional services credit unions offer. Use your credit union for your mortgage and primary savings, and KOHO for your daily spending to earn cash back on every purchase without paying monthly fees.
