The Best Retirement Planning Tool to Use With ChatGPT or Claude in Canada

There is no single "best" retirement planning app built for ChatGPT or Claude in Canada. What works best is a pairing: the Government of Canada's free tools for your official numbers, your own account statements, and an AI assistant to explain the rules and run what-if scenarios. Let the AI teach and check the math. Don't let it be the only source of your numbers.

That may sound less exciting than one perfect app. In practice it's a sturdier setup, and anyone in Ontario can build it in an afternoon. The rest of this article walks through the pieces, how to put them together, what to keep private, and how to tell when the AI has made a mistake.

Why there isn't one "best" tool

AI assistants like ChatGPT and Claude are general-purpose. They don't come with your CPP contribution history, your RRSP balance or your pension details. They only know what you tell them and what they learned in training, and some of that may be out of date or based on American rules.

Canadian retirement rules also change every year. TFSA limits, the OAS clawback threshold and CPP maximums are all indexed or updated each year. An AI assistant may be quoting last year's figure, or a figure from the wrong country. That's why the best "tool" is really a process. Official numbers go in, the AI does the explaining and the calculating, and you check the results.

Marc Pineault, a retirement planner in London, Ontario, sees more people arrive at their first meeting with an AI-built spreadsheet in hand. That's a good sign. It means they have already thought through their questions. The quality of those spreadsheets, though, depends almost entirely on the quality of the numbers that went into them.

The three pieces of a reliable AI retirement setup

1. Your official government numbers

Your most important inputs come from the federal government, not from an AI.

• Your CPP estimate. My Service Canada Account shows your contribution history and an estimated monthly pension. The Government of Canada's Canada Pension Plan page explains how the pension is calculated and links to the sign-in.
• Your OAS eligibility. The Old Age Security page on canada.ca explains residency requirements, deferral and the recovery tax (often called the clawback).
• Your TFSA and RRSP room. CRA My Account shows your exact contribution room. The CRA's TFSA page explains the rules, and the CRA set the 2026 TFSA annual limit at $7,000.

The Government of Canada also offers a free Canadian Retirement Income Calculator. It walks you through CPP, OAS, workplace pensions and savings. Its results make a good, neutral starting point to bring into an AI conversation.

2. Your own statements

Next, collect current balances by account type: RRSP or RRIF, TFSA, non-registered, any LIRA or locked-in accounts, and any defined benefit pension statement. The AI doesn't need account numbers or the names of institutions. It needs to know how much is in each type of account, because each type is taxed differently when the money comes out.

3. The AI assistant itself

This is where ChatGPT or Claude earns its place. Both are good at:

• Explaining a rule in plain English ("What happens to my RRSP at 71?")
• Building a year-by-year table from the inputs you give it
• Comparing two or three scenarios side by side
• Spotting questions you haven't thought to ask yet

Neither one is good at knowing this year's exact thresholds unless you supply them, and neither can see the parts of your situation you leave out.

What to keep private before you share anything

Before you paste a statement or a summary into any AI tool, remove:

• Your Social Insurance Number
• Account and policy numbers
• Your full name, address and exact date of birth (your age is enough)
• Login details of any kind

FSRAO, Ontario's financial services regulator, regularly reminds consumers to protect their personal financial information. The AI doesn't need any of these details to be useful. "I'm 63, my spouse is 61, I have $600,000 in an RRSP" gives it everything it needs.

A worked example: checking the AI's math on a $900,000 portfolio

Here's how the process works in practice, using a made-up Ontario couple.

The inputs. Assume one spouse, age 65, has:

• $600,000 in an RRSP
• $300,000 in a TFSA
• A Service Canada estimate of $1,000 per month in CPP if started at 65 (a round number to make the math easy to follow)

Total portfolio: $600,000 + $300,000 = $900,000.

Question 1: What does CPP look like at 60, 65 and 70?

The CPP rules are set in legislation. According to the Government of Canada, the pension drops by 0.6% for each month you start before 65 and rises by 0.7% for each month you start after 65, up to age 70.

• Starting at 60: 60 months early × 0.6% = 36% reduction. $1,000 × 0.64 = $640 per month
• Starting at 65: $1,000 per month
• Starting at 70: 60 months late × 0.7% = 42% increase. $1,000 × 1.42 = $1,420 per month

If the AI gives you figures that don't match these, it has used the wrong rule. That's your cue to correct it and ask it to redo the table. Our CPP timing guide covers the trade-offs behind the start-age decision in much more depth.

Question 2: What's the minimum RRIF withdrawal at 71?

Under the CRA's prescribed RRIF factors, the minimum withdrawal in the year you turn 71 is 5.28% of the January 1 balance. Suppose the RRSP is still about $600,000 when it becomes a RRIF:

• $600,000 × 5.28% = $31,680 minimum withdrawal that year

This is a fixed percentage, so it's easy to check. If the AI says something like "4%", it's probably mixing up the RRIF minimum with a general rule of thumb about withdrawals. The RRIF withdrawal strategy guide explains how those minimums climb with age.

Question 3: How do the pieces interact?

Now the AI is genuinely useful. You can ask: "Show me taxable income each year from 65 to 75 if I start CPP at 70 and draw $40,000 a year from the RRSP before then." It can build the table in seconds. You then check two or three rows by hand to make sure it isn't drifting.

The point of this example is not the specific dollar figures. Your own numbers will be different. The point is that every key calculation rests on a published rule you can check yourself.

Questions worth asking your AI assistant

Once your inputs are in place, these prompts tend to produce useful, educational answers:

• "Explain how drawing down my RRSP before 71 could change my taxable income later. Use only the numbers I've given you."
• "Show me how OAS recovery tax works using a 15% rate on income above the threshold. Ask me for this year's threshold rather than assuming it."
• "List the questions a retiree in Ontario should consider before converting an RRSP to a RRIF."
• "Compare these two scenarios in a table, and flag any assumption you made that I didn't give you."

That last instruction matters. Asking the AI to name its own assumptions is one of the simplest ways to catch errors.

For a deeper look at specific strategies the AI might raise, the RRSP meltdown guide and the OAS clawback strategy guide give the Ontario-specific background. That makes the AI's answers easier to judge.

Where AI assistants commonly go wrong

From what Marc Pineault sees working with retirees in London, Ontario, a few errors come up again and again:

American rules slipping in. An AI may mention Social Security, 401(k)s, Roth conversions or US-style required minimum distributions. None of these apply in Canada. If you see them, tell the AI you're in Ontario and ask it to start over.

Out-of-date thresholds. OAS clawback thresholds, TFSA limits and CPP maximums change. Always supply the current figure from canada.ca rather than trusting the AI's memory.

Missing provincial tax. Ontario has its own tax brackets and surtaxes, plus the Ontario Health Premium. An AI estimate that uses only federal brackets will understate tax.

Ignoring the survivor picture. Many scenarios assume both spouses live to the same age. Ask the AI what changes if one spouse dies early. Pension splitting, RRIF rollovers and the move to single-person tax brackets can change the picture a lot.

Confident tone, wrong answer. AI tools write fluently even when they're mistaken. A well-formatted table isn't the same as a correct one.

"Use the AI to understand your options, then check the three or four numbers that matter most against your own statements. If a number surprises you, that's usually the one worth a second look." — Marc Pineault, retirement planner in London, Ontario

Where calculators and human review fit

Free calculators and AI assistants complement each other. A calculator applies fixed formulas the same way every time. An AI assistant is flexible and conversational, but less predictable. Using both and comparing the results is a good habit. You can try the free retirement planning calculators on this site alongside the Government of Canada's tools and see whether they broadly agree.

There are also limits that no tool fully covers. Questions about estate planning, insurance, how a defined benefit pension fits with RRIF withdrawals, or how to sequence withdrawals across several account types usually involve trade-offs. Those trade-offs depend on personal priorities as much as on math. An AI can lay out the options clearly. Deciding which trade-offs fit your life is a different kind of conversation.

Many people in London and across Ontario find a middle path works well. They do their own homework with AI and official calculators, then bring the results to a retirement planner for a second set of eyes. Arriving with organized numbers and clear questions tends to make that conversation more productive.

Putting it together

The most reliable retirement planning setup for ChatGPT or Claude in Canada isn't a single product. It's a habit:

1. Get your official CPP, OAS and contribution-room figures from canada.ca and CRA My Account.
2. Collect your balances by account type, with personal identifiers removed.
3. Give those numbers to the AI and ask it to explain, compare and build tables.
4. Check the key calculations against the published rules yourself.
5. Ask the AI to list its assumptions, and correct any that are wrong.

Used this way, an AI assistant becomes a patient tutor that's available at any hour. That's useful for anyone in Ontario who wants to understand their retirement picture before making decisions about it.
