Aurora window closing for southern Canada as solar activity enters quieter phase

The lights fill hotels, restaurants, and the pockets of small tour operators.
How the northern lights have become an economic engine for Arctic communities.

For two years, the night skies over southern Canada offered something rare — a celestial spectacle most people had never witnessed and may not see again in their lifetimes. The sun, following its ancient 11-year rhythm, has begun its long exhale toward a quieter phase, and the auroras that lit up Ontario and British Columbia are retreating northward where they have always truly belonged. What closes as a window for the south opens as an opportunity for the territories above the 60th parallel, where the lights have never really left — and where the human story of place, economy, and wonder is now being written anew.

  • The solar maximum that gifted southern Canadians with vivid aurora displays has passed, and the sun's declining activity means those rare southern sightings will grow scarcer until at least 2031.
  • Northern tourism economies built around the aurora are now racing to consolidate their advantage before the broader excitement fades and competition for a smaller pool of solar-driven displays intensifies.
  • Yellowknife, Whitehorse, and the wider Arctic corridor above the 60th parallel remain structurally immune to the solar downturn, with auroras visible nearly 240 nights a year regardless of the cycle.
  • Territories are navigating the shift differently — Yukon is leveraging aurora arrivals to build repeat visitors around broader experiences, while Nunavut is weighing whether to pivot its Inuit-culture-first brand toward the lights it has long underplayed.

For two years, southern Canadians stepped outside on certain nights to find their skies transformed — purple, pink, and green ribbons overhead that most had never seen before. Those nights are ending. The sun has passed its peak, and as it descends toward its 2031 minimum, the auroras visible from Ontario, Manitoba, and British Columbia will become rare again.

Ethen Sun, a doctoral candidate in astronomy at the University of Toronto, explains that the sun moves between explosive activity and dormancy on an 11-year cycle. The solar maximum arrived roughly eighteen months ago; from here, the coronal mass ejections and geomagnetic storms that paint the sky will gradually subside. The decline is steady, the trajectory clear.

The far north will barely notice. Above the 60th parallel, the auroral oval sits almost directly overhead, and places like Yellowknife average 240 nights of aurora visibility per year. The best viewing runs September through April, with peaks around the equinoxes — but even in the Arctic, some of the intensity of recent years will soften as the solar storms quiet.

The northern territories have been riding the solar maximum hard. Yukon deliberately positioned itself as an aurora destination during the peak years, and tourism reached $484 million in 2025. Tour operator Aaron Ratko has watched visitors arrive in minus-40 temperatures just to chase the lights — and return in milder seasons for landscapes, culture, and day tours. The aurora opens the door; other experiences keep people coming back.

Northwest Territories has built its identity almost entirely around the lights, with roughly 41 percent of visitors citing the aurora as their primary draw. Aurora Village in Yellowknife anchors an entire local economy — hotels, restaurants, small operators — and its team tracks the solar cycle closely to help visitors understand what they're witnessing. Even so, the unpredictability of the sky remains part of the appeal.

Nunavut has taken a quieter path, marketing Inuit heritage, wildlife, and landscape rather than the aurora itself. But as southern viewing fades and competition among the three territories grows, CEO Alex Stubbing has suggested that may change. The question facing all three is whether to compete aggressively for aurora tourists — or trust that the lights, as they always have, will do the work themselves.

For the past two years, people across southern Canada have stepped outside on certain nights to find the sky transformed—ribbons of purple, pink, and green dancing overhead in ways most of them had never seen before. Those displays are ending. The sun is entering a quieter phase of its natural 11-year cycle, and the window for watching the northern lights from places like Ontario, British Columbia, Saskatchewan, and Manitoba is closing.

Ethen Sun, a doctoral candidate in astronomy at the University of Toronto, explains the mechanics simply enough. The sun oscillates between periods of explosive activity and dormancy. We passed the peak—the solar maximum—about eighteen months ago. From here, the intensity will decline steadily until around 2031, when the sun reaches its minimum. Right now the activity is still relatively high because we're still in the upper part of the cycle, but the trajectory is downward. During the maximum phase, the sun unleashes coronal mass ejections, solar flares, and geomagnetic storms. Those storms are what paint the sky. As they fade, so do the auroras visible from the south.

The far north will barely notice. Above the 60th parallel—in the Yukon, Northwest Territories, and Nunavut—the auroral oval, that halo of light that encircles the magnetic poles, sits almost directly overhead. People living and traveling there can expect to see the northern lights almost every night, regardless of where the sun is in its cycle. Yellowknife alone averages 240 nights of aurora visibility per year. The best viewing window everywhere, Sun notes, runs from September through April, with especially vivid displays around the spring and autumn equinoxes. But even in the Arctic, some of the intensity and color variation of the past two years will fade as the solar storms subside.

The tourism industry in the northern territories has been riding this peak hard. Yukon's government deliberately positioned the territory as an aurora destination during the 2023-to-2025 solar maximum, and it paid off. Tourism brought in $484 million to the territory in 2025, with northern lights serving as a primary draw for visitors from the United Kingdom, Germany, Switzerland, and Australia. Aaron Ratko, who runs a tourism company in Yukon and sits on the board of the Wilderness Tourism Association, has watched the pattern. People arrive in winter at minus-40 degrees specifically to chase the lights. If they return, they often come back in fall when the weather is milder, and they branch out into other experiences—day tours, landscape viewing, cultural activities. The aurora gets them in the door, but it's not always what keeps them coming back.

Northwest Territories has built its tourism brand almost entirely around the northern lights. About 41 percent of tourists to the territory cite the aurora as their primary reason for visiting. Marie-Soleil Lacoursière, who manages Aurora Village in Yellowknife, understands the economic weight: the lights fill hotels, restaurants, supermarkets, and the pockets of small tour operators. Hideo Nagatani, a senior advisor at the same company, tracks the solar cycle closely and blogs about it, helping customers understand what they're seeing and positioning the Northwest Territories as one of the planet's most reliable aurora spots. Yet even he notes that the unpredictability of what appears in the sky—the fact that you might see something beyond what you expected—is part of what draws people. The solar cycle matters, but it's not everything.

Nunavut has taken a different approach. Alex Stubbing, CEO of Travel Nunavut, says the territory markets itself on Inuit culture and heritage, on mountain ranges and wildlife and landscape. Auroras happen there, certainly, and visitors see them, but no trips are built around them. As the solar maximum wanes and the three northern territories consolidate their position as the world's most reliable aurora destinations, Stubbing has indicated that Nunavut might reconsider that strategy. The competition for aurora tourists will intensify as southern viewing fades. The question now is whether the territories will fight for that business or whether they'll let the lights do the work themselves.

The extra colours and the extra movement are generally when there's some sort of storm going on.

So people in Toronto or Vancouver had a two-year window where they could actually see the northern lights from home. That's unusual?

Model

Very. The sun goes through these cycles, and we just happened to be at the peak. Geomagnetic storms were pushing the auroral oval further south than normal. It won't happen again for another eleven years.

Inventor

And the people in Yellowknife or Whitehorse—they're not losing anything?

Model

Not really. They see the lights almost every night anyway. The aurora sits directly over them. What they might lose is some of the extra color and movement that comes with the really intense solar storms. But the baseline never changes.

Inventor

The tourism operators seem pretty calm about this shift. Why?

Model

Because they've already built their business on reliability. Yellowknife gets 240 nights of aurora a year with or without the solar maximum. That's a selling point in itself. And people who come for the lights often stay for other reasons—the landscape, the culture, the experience of being in the Arctic.

Inventor

Is Nunavut worried about being left behind?

Model

They might be starting to think about it. Right now they market culture and wildlife. But as the southern viewing window closes and more aurora tourists head north, Nunavut could position itself as a serious competitor. The lights are there. It's just a question of whether they want to make that their story.

Inventor

What happens in 2031 when the sun hits minimum?

Model

The lights don't disappear. They just get dimmer and less frequent everywhere except the far north. The Arctic stays the Arctic. The south goes back to what it was before 2023—occasional, rare, special when they happen.
