The Guaranteed Income Supplement, usually called GIS, is Canada's monthly top-up for low-income seniors who already receive the Old Age Security (OAS) pension. It is paid by Service Canada, it is not taxable, and it is income-tested: the less income you have besides OAS, the more GIS you receive, up to a maximum that depends on whether you are single or part of a couple and on what your spouse or common-law partner receives. For October to December 2026, the maximum is $1,138.90 a month for a single, widowed or divorced pensioner and $685.56 a month for a pensioner whose spouse or partner receives the full OAS pension. If your spouse or partner receives neither OAS nor the Allowance, your maximum is also $1,138.90 a month, but the combined income limit is higher.

This site explains GIS in plain English: who can claim, how the income test counts (and does not count) each kind of income, the maximum payments, how to apply, when enrolment is automatic and when it is not, how payments arrive, what happens when your income changes, the July renewal, overpayments and appeals, and how GIS differs from OAS, the Canada Pension Plan (CPP) and the Allowance. Every headline figure comes from Service Canada or Canada.ca, for October to December 2026.

Key numbers at a glance (October to December 2026, Service Canada)

Single, widowed or divorced: income other than OAS less than $23,112 a year; maximum GIS $1,138.90 a month.
Spouse or partner receives the full OAS pension: combined income less than $30,528 a year; maximum GIS $685.56 a month.
Spouse or partner receives the Allowance: combined income less than $42,768 a year; maximum GIS $685.56 a month.
Spouse or partner receives neither OAS nor the Allowance: combined income less than $55,392 a year; maximum GIS $1,138.90 a month.
Work exemption: the first $5,000 of employment or self-employment income is fully exempt, and 50% of the next $10,000 is exempt.
Renewal: GIS is reviewed every July from your tax return — file by 30 April every year to avoid an interruption.

The two mistakes that cost seniors money

The first mistake is assuming you do not qualify without checking. GIS is not a fixed amount that you either get in full or not at all: it tapers as income rises, so a senior with a modest CPP pension and a small workplace pension may still receive a partial GIS worth hundreds of dollars a month. The income test counts CPP, private pensions and RRSP withdrawals, but it does not count OAS itself, GIS itself, or withdrawals from a Tax-Free Savings Account (TFSA). The income-test page works through each source, so a quick "I have a pension, so I get nothing" guess is replaced by a real calculation.

The second mistake is missing the tax return. GIS is renewed automatically only if Service Canada has your income — and that comes from your tax return. Seniors who owe no tax sometimes stop filing, and then the July renewal cannot happen and payments stop. Filing every year, even with no tax to pay, is the single cheapest way to protect a GIS payment, and the renewals page explains the July letter to watch for.

An honest note about the figures you may see elsewhere

Several websites still show $1,123.17 a month for a single pensioner with a $22,800 income limit. Those are the July to September 2026 figures, and they are out of date: from October 2026 the single maximum is $1,138.90 with a $23,112 limit, after the quarterly indexation. If a page you are reading quotes $1,123.17 as the current figure, it has not been updated. Older figures still circulating — $1,109.85, $1,086.88 and $1,066.75 for a single pensioner — are earlier quarters again. This site uses the October to December 2026 table throughout, and it does not publish January to March 2027 rates, which were not available when this site was built.

How this site is organized

Start with who can claim for the age, residence and sponsorship rules, then the income test and the maximum payments for the money. How to apply and automatic enrolment cover the two routes in, payments covers dates and direct deposit, and changes and renewals covers the July review. The remaining pages cover overpayments and appeals, comparisons with OAS, CPP and the Allowance, and myths.

Not the same benefit as elsewhere. GIS is a Canadian federal benefit. It is not the United Kingdom's Pension Credit, the United States' Supplemental Security Income, or Australia's Age Pension, even though all four top up low retirement incomes. Different countries, different payers, different rules — the comparisons page keeps them apart.

General information only. This page explains the Guaranteed Income Supplement in plain English. It is not legal, financial, or tax advice, and it cannot decide whether you qualify. Only Service Canada can decide a claim. Rates and rules change over time — the figures here are for October to December 2026 unless another period is stated — so always confirm the current position with Service Canada or Canada.ca before you act on it.
