Where do I find the tax treaty text that is actually in force?
You need more than the treaty. Many agreements were modified collectively by the multilateral instrument, so the operative text is the original treaty as changed by that instrument, read together with what each of the two countries chose. That means three documents rather than one: the treaty, the modifying instrument, and each country's list of covered agreements, reservations and notifications. A provision changes only where both countries' positions line up, and it changes from a date that follows their own ratification steps. Working from a downloaded treaty alone is a common way a confident treaty conclusion turns out to be wrong.
What does the MLI change in a treaty?
Whatever the two countries both agreed it should. It was written as a menu rather than a single amendment, which is why two treaties can be modified quite differently. Anti-abuse provisions are the part most often met in practice, along with changes to how residence conflicts and dispute resolution are handled. What matters for a particular file is not the instrument in general but the intersection of two countries' positions: where one reserved on a provision and the other did not, the provision does not enter their treaty. So the question is always about a specific pair of countries and a specific article.
Has the MLI changed the treaty between my two countries?
That depends on whether both of them listed that treaty as covered, and on what each notified for the article you care about. Both conditions have to be met. A country can be a party to the instrument and still have left a particular treaty out of its list, and it can include the treaty while reserving on the very provision you are reading. The check is mechanical but has to be done per country, per treaty and per article, and the answer should be recorded on the file with the date it was checked, because positions can be updated.
Why does my adviser's treaty wording differ from the government website?
Usually because one of you is reading the original agreement and the other is reading it as modified. Sites publish the signed treaty, sometimes alongside a consolidated reading that incorporates the modifications, and the two are not the same document. A consolidated version is a reading aid rather than the legal text, so where it matters the position should be traced back through the modifying instrument and both countries' notifications. The disagreement is worth resolving properly rather than splitting the difference: an article that was changed and an article that was not produce different answers on the same facts.
From what date do the modified treaty provisions apply?
From dates that follow each country's own ratification steps rather than from a single global start, and they differ by type of tax, since provisions affecting amounts withheld at source take effect on a different footing from those affecting other taxes. The consequence for a file spanning several years is that the same article can carry one meaning in an earlier year and another in a later one. Where a position covers a period on both sides of the change it has to be stated year by year, with the operative text identified for each year rather than once for the whole file.
Does the MLI give me a right to arbitration in a treaty dispute?
Only if both countries opted into those provisions for that treaty. The dispute resolution parts of the instrument were among the optional elements, so they are present in some modified treaties and absent from others. Where they are absent, the treaty's own dispute route remains what it always was, a negotiation between the two administrations with no obligation on them to reach agreement. That distinction matters early, because the strength of a dispute position depends partly on what happens if the two countries do not agree. Establish which route exists before deciding how to present the case.
How do I find out whether Canada has a tax treaty with a particular country?
Canada has income tax conventions in force with more than ninety jurisdictions, and the Department of Finance publishes the status of each one — in force, signed but not yet in force, or under negotiation. Read two things, not one: the treaty text, and whether the Multilateral Instrument has modified it. A treaty printed before that modification can give you the wrong answer on entitlement.

What is double taxation?
Double taxation means the same income being taxed by two authorities. It comes in two forms: juridical, where two countries each tax one person on one amount, and economic, where two different people are taxed on the same underlying profit — a company on its earnings and a shareholder on the dividend paid out of them. Relief comes from a treaty, a foreign tax credit, or an exemption, and which one applies depends on the income type. How to avoid double taxation sets out the routes.
