Credit-union deposits are not insured by CDIC; each province runs its own deposit-insurance fund for the credit unions it charters. Those funds differ from CDIC in structure and in generosity, and in four provinces the coverage has no dollar cap at all. The name-by-name table of who insures which institution lives in our deposit insurance guide; the system behind that table works differently from CDIC, starting with who runs it.
Two systems built for the same job
Canada runs two parallel deposit-insurance systems, and neither is the junior one. Each exists by statute and is funded by the institutions it covers, so that an institution’s failure is not its depositors’ failure.
The practical difference for a saver: with a credit union, the rules that matter are set by the fund in the province where that credit union is chartered, and those rules vary more than CDIC’s do.
The unlimited provinces
The two systems, side by side:
| CDIC | Provincial funds | |
|---|---|---|
| Institutions covered | Banks, federally regulated trust and loan companies, federal credit unions | Credit unions and caisses populaires chartered in that province |
| The cap | $100,000 per insured category | Varies by province (no cap in four provinces, fixed caps elsewhere) |
| Who runs it | A federal Crown corporation | A provincial fund or agency (one per province) |
| Funding | Premiums paid by member institutions | Assessments paid by the province’s credit unions |
The cap row is where the provincial side pulls ahead. In British Columbia, Alberta, Saskatchewan and Manitoba, the provincial fund guarantees credit-union deposits in full, with no dollar limit. Ontario sits between the two models: registered accounts are covered without limit, and non-registered deposits up to $250,000, as Ontario’s financial regulator sets out. Quebec’s caisse system is the counterpoint at up to $100,000, the same figure as CDIC, and the Atlantic funds commonly cover up to $250,000. The per-insurer detail sits in the table on the deposit insurance guide linked above.
Unlimited means unlimited on deposits. Savings, chequing, GICs and term deposits are inside the guarantee; it does not turn investments into deposits, so mutual funds or securities bought through a credit union’s dealer arm sit outside it in every province.
For anyone holding more than CDIC’s per-category arithmetic comfortably covers, this is a real structural difference: at a credit union in an unlimited province there is no ceiling to arrange deposits around. The fund’s own site (British Columbia’s CUDIC, for example) remains the authority on what counts as a deposit under its rules.
What “provincially regulated” means for a saver
A provincially chartered credit union is incorporated under provincial law, supervised by that province’s financial regulator, and covered by that province’s fund. Three practical consequences follow.
First, membership: credit unions are owned by the people who bank there, so opening an account usually includes buying a small membership share. Second, the deposit-insurance fine print comes from the fund: how registered accounts are treated, whether joint deposits get separate coverage, and how interest is counted all vary by province. Third, coverage attaches to the credit union’s charter, not the saver’s address: deposits at a credit union chartered in an unlimited province are guaranteed by that province’s fund regardless of where the member lives.
None of this changes how the products behave. A GIC at a credit union works like a GIC anywhere else, and credit-union offers compete against bank offers on the same terms.
The federal exception, and how to check
One wrinkle keeps the word “credit union” from settling the question by itself: a credit union can continue federally under the Bank Act. A federal credit union is regulated by OSFI and insured by CDIC under the $100,000-per-category structure, not by a provincial fund. The sign out front reads the same either way.
So check rather than assume. Every offer on our boards names the institution’s deposit insurer in its product details, and our methodology explains where that field comes from and how it is kept accurate. CDIC publishes its member list, and each provincial fund publishes its own; between those, the question of who stands behind any Canadian deposit is answerable in a minute or two.
Before you move money
The order of operations is short: confirm who insures the institution, confirm the cap that applies to your situation, then compare the actual offer. If the offer is a GIC and the product itself is new to you, our explainer on how GICs work in Canada covers it from the top. Credit-union rates sit alongside bank rates on the GIC board and the savings board, insurer stated on each, and a rate alert will flag a target rate whichever kind of institution posts it.
Frequently asked questions
Is provincial deposit insurance as safe as CDIC?
It is a different backer, not a lesser one. CDIC is a federal Crown corporation; the provincial funds are statutory bodies with their own reserves, and in some provinces the guarantee carries legislative backing from the province itself. What a saver controls is identical in both systems: know which fund covers your institution and what its cap is.
How do I tell whether a credit union is federal or provincial?
Check the deposit-insurer line in the offer’s details on our boards, or CDIC’s member list, where federal credit unions appear. If an institution is not a CDIC member, its provincial fund covers it, under that fund’s rules.
Does unlimited coverage include TFSAs and RRSPs?
In the unlimited provinces the guarantee applies to deposits of every kind at the credit union, registered accounts included. The distinction that matters is deposit versus investment: a GIC inside a TFSA is a deposit; a mutual fund inside the same TFSA is not.
Do I have to live in the province to be covered?
Coverage follows the credit union’s charter rather than the member’s address. Whether you can join a given credit union from another province is a membership question, and the answer varies by institution, but deposits accepted are deposits covered.
