On September 9, 2025, the Toronto Stock Exchange (TSX) made headlines after reaching a new all-time high. The index climbed 35.28 points, closing at 29,063.01, breaking its previous record set just a few days earlier.

• This achievement was not random. Two major factors pushed the market up:
• A blockbuster mining merger involving Teck Resources.
• Rising energy stocks fueled by higher oil prices.
• Together, these events created strong investor confidence, lifting the Canadian market to historic levels.

What is the TSX?

The Toronto Stock Exchange is Canada’s biggest stock market and one of the largest in the world. It is where companies list their shares so people can buy and sell them.

The TSX includes many industries, but Canada is especially known for energy and mining companies. These sectors are very important to the Canadian economy because the country has large reserves of oil, gas, and minerals.

When energy or mining stocks move up, the TSX usually follows. That is why the merger and oil price changes had such a strong effect on this day.

The Big Mining Merger: Teck and Anglo American

The highlight of the day was the news that Teck Resources, a Canadian mining giant, announced plans to merge with Anglo American, a major mining company from the United Kingdom.

This merger is valued at about $53 billion, making it one of the largest mining deals in recent years.

As soon as investors heard the news, Teck’s shares jumped by 11.5% in just one day. That kind of increase shows how much excitement there was in the market.

Why the Merger Matters

• Mining is more than just digging up rocks. It provides essential materials that modern life depends on:
• Copper: used in electric vehicles, renewable energy systems, and electronics.
• Coal: still used in some industries, though its use is declining.
• Zinc: used for making steel stronger.
• Other metals: needed for construction, technology, and manufacturing.

By merging, Teck and Anglo American would become a mining powerhouse. The new company would have greater resources, global reach, and the ability to meet rising demand for metals, especially copper.

Investors saw this as a sign that the mining industry has strong growth potential. With the world moving toward clean energy and electric vehicles, demand for copper is expected to skyrocket. That is why the merger was seen as such positive news.

Energy Stocks and Oil Prices

The second big factor lifting the TSX was rising oil prices. Energy stocks climbed about 1.6% during the day.

Canada is one of the world’s top oil producers, and many energy companies are listed on the TSX. When oil prices rise, these companies’ profits usually increase. This leads to higher share prices, which in turn lifts the entire index.

Even a small move in oil prices can have a major effect because energy makes up such a large part of Canada’s economy.

U.S. Markets Also Rose

Canada’s stock market does not move in isolation. On the same day, U.S. markets also performed strongly. The S&P 500, a major American stock index, hit a record high too.

The reason was investor belief that the U.S. central bank might cut interest rates soon. Lower interest rates make borrowing money cheaper, which encourages people and companies to spend and invest more. That usually helps stock markets go up.

Since Canada’s economy is closely linked to the U.S., when American markets rise, Canadian markets often benefit too.

Why Investors Reacted So Strongly

• Investors watch the market carefully, and their reactions are often based on a mix of numbers and emotions.
• Confidence: The merger gave people confidence that mining companies see a strong future.
• Excitement: The 11.5% jump in Teck’s shares showed how excited people were about the potential profits.
• Stability: Rising oil prices suggested stability for Canada’s energy industry, another big positive.
• When investors feel optimistic, they are more willing to buy shares. This demand pushes the index higher.

What This Means for Canada

• The TSX reaching 29,063.01 is more than just a statistic. It shows that Canada’s economy is in a strong position right now.
• Global Interest: Foreign investors may be more likely to put money into Canadian companies.
• Business Growth: Canadian companies can use this confidence to expand and take on bigger projects.
• National Pride: Record highs also bring a sense of pride and optimism to ordinary Canadians, even if they don’t directly invest.

Background on Teck Resources

• Teck Resources is one of Canada’s most important mining companies. It produces copper, zinc, steelmaking coal, and other materials.
• The company is seen as a leader in Canada’s resource industry, and its decisions often influence how investors view the mining sector as a whole.
• The planned merger with Anglo American would make Teck part of one of the largest mining groups in the world.

Background on Anglo American

Anglo American is a London-based mining company with operations around the globe. It mines copper, platinum, diamonds, and iron ore.

By merging with Teck, Anglo American gains more access to Canada’s rich natural resources, while Teck gains global reach. Together, they would become stronger and more competitive in the worldwide mining market.

Why Copper is So Important

• Copper played a big role in why this merger made investors so excited.
• Electric vehicles (EVs) use three to four times more copper than traditional cars.
• Solar panels and wind turbines need copper for wiring and energy transfer.
• Modern infrastructure, like power grids and high-speed internet, also requires copper.

As the world shifts toward clean energy and electrification, demand for copper is expected to rise sharply. A company that controls large copper supplies could become very profitable.

Looking Back: TSX History

• The TSX has been around for more than 160 years. Over time, it has seen many ups and downs.
• In the early 2000s, the index rose sharply during the oil boom.
• During the 2008 global financial crisis, the TSX fell heavily.
• In recent years, it has grown steadily, reflecting Canada’s strong resource industries.
• Reaching 29,063.01 is a new milestone in this long history, showing how far the market has come.

Risks Still Remain

• Even though this was a record-breaking day, risks remain for the Canadian economy.
• Oil Volatility: Oil prices can fall as quickly as they rise, hurting energy stocks.
• Global Uncertainty: Political or economic troubles in other countries can affect Canada’s exports.
• Merger Challenges: Large mergers often face government review and regulatory hurdles.
• Investors will watch closely to see if the Teck-Anglo deal goes through smoothly and whether energy prices remain stable.
• The TSX hit a new record high of 29,063.01.
• A huge mining merger between Teck Resources and Anglo American boosted excitement.
• Teck’s shares rose 11.5% in one day.
• Energy stocks also went up as oil prices increased.
• U.S. markets were strong too, helping Canada.
• Investors believe mining, especially copper, has a bright future.

The record shows confidence in Canada’s economy.

The Toronto Stock Exchange hitting a record high on September 9, 2025, was the result of confidence in Canada’s mining future and rising energy stocks. The planned Teck-Anglo American merger gave investors hope that Canada will play a central role in the global mining industry, especially in the copper market.

While risks remain, the day will be remembered as a milestone showing the strength and potential of Canada’s economy
