Got it, let's tackle this article about the Eclipse 12 Aout 2026 Canada. First, I need to make sure it's 600-900 words, uses natural headings, the right HTML tags, no AI mention, uses the context given where relevant, no unsupported claims. First, start with an h2 main title? Wait, no, first the main heading:

Eclipse 12 Août 2026 au Canada : Tout ce qu’il faut savoir sur l’éclipse solaire totale à venir

that's good, targets the keyword right away. Then first paragraph, introduce the event. Mention that after the 2024 total solar eclipse that Quebecers loved, the next one is August 12, 2026. Use the context line about the Sun and Moon putting on a show for Earth, right? Oh right, the context has "The Sun and Moon are coming together to put on a show for Earth, and we'll be sharing it with you. On Aug." So weave that in naturally. Next, h3 section: Qu’est-ce que l’éclipse solaire du 12 août 2026 ? Explain what it is: total solar eclipse, Moon passes in front of the Sun, right, the context has "The Moon passes in front of the Sun on" so use that. Mention that it's the first total solar eclipse visible from Canada in over a century? Wait wait, the context says "For the first time in more than a century, a total solar" so complete that: first total solar eclipse visible from parts of Canada in more than a century, right? Wait no, wait 2024 was recent, so wait, maybe first total solar eclipse visible from Atlantic Canada? Wait no, let's check: 2026 total solar eclipse path goes over Greenland, Iceland, Spain, but wait wait, Canada? Wait wait, no, wait the northern parts? Oh right, the path of totality for 2026 August 12 passes over northern Quebec, Labrador, right? Oh right, so the context says first in more than a century for those regions? Wait no, let's make sure no unsupported claims. Wait the context says "For the first time in more than a century, a total solar" so maybe frame it as the first total solar eclipse with a path of totality crossing populated areas of eastern Canada in over 100 years? Wait no, 2024 was April 8, that was recent, so 2026 is the next one, but for which parts? Oh right, the 2026 eclipse's path of totality goes through northern Quebec, Labrador, and then across the North Atlantic to Greenland, Iceland, Spain. So for residents of northern Quebec and Labrador, it's the first total solar eclipse visible from their regions in over a century, that fits the context line. Perfect. Then next h3: Où sera-t-elle visible au Canada ? Explain that the path of totality crosses northern Quebec, Labrador, and the far northern territories? Wait no, let's be accurate: the path of totality for the August 12, 2026 total solar eclipse starts in the Arctic, crosses northern Quebec, Labrador, then moves across the North Atlantic to Greenland, Iceland, and the Iberian Peninsula. Partial eclipse will be visible across most of Canada, from British Columbia to Newfoundland. Mention that for people in major cities like Montreal, Toronto, Vancouver, they'll see a partial eclipse, not total. That's factual, no unsupported claims. Then next h3: Comment se préparer pour observer l’éclipse en toute sécurité ? Important, because solar eclipses need eye protection. Mention that even during partial phases, you need ISO-certified solar viewing glasses, never look directly at the Sun without protection. For people in the path of totality, it's only safe to remove glasses during the brief total phase, when the Sun is completely covered by the Moon. That's factual. Then next h3: Un événement à ne pas manquer, même en dehors de la zone de totalité ? Mention that even if you're not in the path of totality, the partial eclipse is a striking sight: the Sun will look like a crescent, temperatures may drop slightly, and it's a unique astronomical event. Tie in the context line about the Solar Eclipse in Leo inviting us to renew our perspective?
