Tax withheld is not necessarily the final answer
A Canadian pension payment arrives with tax already deducted, and your Argentine accountant still asks about the full amount. That can look like the beginning of paying twice. It is actually the point where the payment's classification, your residence and any treaty relief need to be examined together. The bank deposit shows what you received; it does not establish the final allocation of taxing rights.
Canada and Argentina have a tax treaty in force, published through Canada's Department of Finance. It addresses how the countries' tax systems interact, including competing residence claims and double taxation. CRA administers the Canadian side, while ARCA (formerly AFIP) administers the Argentine side. The treaty text and the procedures used to claim its treatment are related, but they are not the same document.
Read a treaty question as a question about a particular person, income item and period. Saying that the countries have an agreement is only the beginning. To find the relevant treatment, an adviser needs to know what was paid, who paid it and which residence position applies. A description such as money from Canada is too broad to support a useful answer.
Residence comes before a claim for treaty treatment
Begin with each country's domestic residence rules. If only one country regards you as resident, the analysis differs from a case in which both do. If both claim residence, the treaty provides a tie-breaking framework. It is a legal sequence to apply to the facts, not permission to choose the country with the lower expected bill or the simpler online filing system.
Your living arrangements and personal and economic connections can matter to that examination. The centre of vital interests is a way of considering those connections within the applicable treaty test, not a slogan meaning wherever you feel most at home. Provide a dated record of your homes, family circumstances and working arrangements. Ask the adviser to explain which facts support the result rather than supplying only a country name.
The treaty conclusion also needs a period. A move-year answer may not describe the whole preceding year or every year afterwards. Keep any qualifications with the written advice, especially where the household has not moved together or plans remain unsettled. If the facts change, the earlier conclusion needs review before it is repeated to a payer or copied into another declaration.
Pensions need their actual names and payment records
Pension is a convenient household word, but a tax analysis needs the precise payment type. Give the adviser the payer's documents rather than combining public pension payments, an employer pension and registered-plan withdrawals into one budget line. Regular receipts and a planned withdrawal also need to be described accurately. Do not assume the treatment of one payment establishes the treatment of every other retirement account.
Keep the gross payment, withholding and net receipt visible. The tax already deducted may be relevant to the final calculation or a claim for relief, but its presence does not prove that the withholding was correct for your circumstances. Ask whether the payer needs residence documentation and whether any procedure is required to obtain the applicable treaty treatment. A promise of a universal pension withholding rate would skip that necessary work.
Payment logistics belong in a separate column. Having the pension deposited in Canada before transferring it to Argentina may be convenient, but the route does not define the income's treaty classification. Likewise, a currency conversion does not explain which country can tax the pension. Keep the payment statement and the transfer receipt because they answer different questions about the same money.
Relief from double tax can still involve two filings
The treaty is intended to address double taxation, not to promise that a person with connections to both countries files only once. A country may retain a filing or disclosure requirement even where treaty treatment changes the tax due. Ask separately what must be reported, where tax may be charged and how relief is claimed. Conflating those questions can produce either an unnecessary return or a missed obligation.
Depending on the applicable rules, relief may involve recognising tax paid in the other country or applying a limit on taxation. The mechanism must be checked for the income in question; do not assume that every deduction becomes a fully recoverable credit. Give both advisers evidence of payments and assessments. A calculation based on an expected foreign tax amount may need attention if the eventual assessed amount differs.
Avoid filing an additional return merely to feel safer without understanding its basis. Equally, do not omit a required return because a treaty exists. Ask for a filing map naming the country, period and obligation, together with any relief claim that depends on it. That turns a broad assurance about avoiding double taxation into a set of instructions you can actually carry out.
Keep one set of facts between the two advisers
Use the same income schedule and residence chronology on both sides. Differences in legal treatment may be legitimate; differences caused by one adviser receiving a net figure and the other a gross figure are avoidable. Identify the currency and the supporting record for each amount. Ask which conversion convention each filing requires rather than applying the exchange rate used by your transfer app to every tax calculation.
The final advice should distinguish a settled conclusion from a question awaiting confirmation. If a payer must change withholding or an authority must process a claim, record who is responsible for the next action and retain the response. Keep the treaty reasoning with the return, not just in an email you may lose. Next year's adviser should be able to follow the position without recreating the move.
For an ordinary household, the useful outcome is a clear explanation of each recurring payment and what happens when circumstances change. A new pension withdrawal or a return to Canada may require another review. The treaty remains the framework, while your facts determine the application. That is a stronger basis for planning than assuming the first cross-border return settled every future transaction.

Questions Canadians ask about this
Is there a Canada–Argentina tax treaty?
Yes, a treaty is in force. Start with the Department of Finance Canada treaty materials on canada.ca and use the current text for the specific issue being assessed.
Does the treaty mean I file in only one country?
No blanket exemption from a second filing follows from the treaty's existence. Reporting obligations and relief from double taxation need separate examination.
Will my Canadian pension be taxed only in Canada?
Do not assume that result. Your residence, the payment's precise classification and the applicable treaty provisions need review, along with evidence of any tax already withheld.
Can I choose my treaty residence?
The treaty's tie-breaking framework applies to the facts where domestic residence claims overlap. It is not an election based on where you would prefer to pay tax.
