How to Build a GIC Ladder

What a GIC ladder is

A ladder splits one amount into equal pieces, called rungs, and buys a different term with each. The classic structure is five rungs across one to five years.

With $50,000 you buy $10,000 each of a 1, 2, 3, 4 and 5-year GIC. At the end of year one the shortest rung matures. You either take the cash or reinvest it into a new 5-year GIC. At the end of year two the original 2-year rung matures, and so on.

After five years every rung has been replaced by a 5-year GIC, and one of them still matures every single year. That is the whole trick: you end up earning 5-year rates on the entire balance while a fifth of your money becomes available annually.

Building one, step by step

1. Decide how much and how often you need access

The rung length, not the number of rungs, determines how often money frees up. One-year rungs give annual access. If you need cash more often than that, use six-month rungs; adding more rungs just makes each piece smaller.

2. Get real rates for every term

Posted branch rates and brokerage GIC rates for the same term routinely differ, sometimes by a lot. A brokerage GIC desk shows dozens of issuers on one screen, which makes it straightforward to buy each rung from whoever pays best that day.

3. Split the money evenly and buy the terms

Equal rungs keep the maturity schedule even and the average rate predictable. Uneven rungs are fine if you know a particular year needs more cash, but they make the ladder harder to reason about.

4. Set maturity instructions deliberately

This is the step people skip. Many institutions auto-renew a maturing GIC into a similar term at posted rates unless told otherwise, and posted renewal rates are frequently worse than what you could get by shopping that week. Set instructions to deposit to cash, then reinvest by hand.

What laddering actually costs

On a normal rate curve, where longer terms pay more, a ladder finishes behind putting everything into the longest term. That is not a flaw, it is the price of the liquidity, and the size of it surprises people.

Take $50,000 across five rungs at 4.00%, 4.05%, 4.10%, 4.15% and 4.25%, reinvesting each maturing rung at the five-year rate, over a five-year horizon.

The ladder gives up $177 over five years against locking everything into the longest term, which is about 0.07% a year. In exchange, roughly $10,000 becomes available every year without breaking anything.

It also beats rolling one-year GICs by $557, because permanently taking the shortest rate on the curve is a worse deal than most people realize.

You can build your own ladder, edit every rung rate and see the full maturity schedule in the GIC ladder calculator.

What happens when rates move

This is the part a ladder is actually for.

If rates rise, only the maturing rung is stuck at the old rate, and it renews at the new higher one. You capture the increase gradually rather than watching a five-year lock-in sit below market.

If rates fall, the same mechanism runs in reverse. Maturing rungs renew lower, but one at a time, so the blended rate drifts down slowly rather than dropping all at once.

A ladder is not a way to beat the rate cycle. It is a way to make being wrong about it cost less, which for money you might actually need is usually the better objective.

The tax problem, and where to put a ladder

GIC interest is fully taxable as ordinary income at your marginal rate. There is no dividend tax credit and no 50% capital gains inclusion, which makes it the least tax-efficient investment income in Canada.

Worse, Canada's accrual rule requires you to report GIC interest in the year it is earned, not the year it is paid. A compounding GIC that pays nothing until maturity still generates a T5 and a tax bill in the intervening years, on money you have not received.

Applied to a ladder, that means a taxable ladder produces a T5 every year on interest that may still be locked inside a rung. Inside a TFSA, RRSP or FHSA, none of that applies and the ladder is purely a liquidity and rate-averaging tool.

The practical rule: fill registered room with the ladder first, and only put the overflow in a taxable account.

Deposit insurance across a ladder

GICs at CDIC member institutions are insured up to $100,000 per depositor, per insured category, per institution. Deposits held individually, jointly, in a TFSA, in an RRSP, in a RRIF and in an FHSA are separate categories, each with its own $100,000 at the same bank.

A ladder built across several issuers spreads that exposure automatically, which matters once the total gets large. Provincial credit unions are covered by provincial insurers instead, and several provinces offer unlimited coverage on credit union deposits.

When a ladder is the wrong tool

If the money has a single known date, a single GIC matching that date is simpler and pays more. A down payment closing in 24 months belongs in a two-year GIC, not a ladder.

If the money might be needed at any moment, a high-interest savings account is the right home. A ladder gives scheduled access, not immediate access.

And if the horizon is genuinely decades away, the real question is whether guaranteed products belong there at all. GICs protect dollars, not what dollars buy, and over thirty years inflation is the bigger risk than volatility.
