Canada's benchmark stock index wrapped up another solid quarter on Tuesday, extending its winning streak to eight consecutive quarters — the longest such run in nearly three decades. But the S&P/TSX Composite's 6.4% gain in the second quarter still fell well short of the red-hot U.S. market, where the S&P 500 surged 14.9% over the same period.
The TSX finished the day up 0.1% at 34,856.99, according to Reuters data. The modest uptick capped a quarter that saw the index climb steadily, supported by gains in financials and technology stocks. Electronics manufacturer Celestica jumped 6.2% on the final day, adding to the positive tone.
Strong GDP Data Provides Tailwind
One of the key drivers behind the TSX's quarterly performance was better-than-expected economic data. Canada's economy grew 0.5% in April compared to March, the strongest monthly expansion in nine months. That beat analyst forecasts and signaled that the domestic economy was gaining momentum heading into the spring.
Strong GDP growth typically supports corporate earnings and investor sentiment, as it suggests consumers are spending and businesses are investing. For Canadian investors, the data reinforced the view that the economy is on solid footing, even as global headwinds persist.

Trade Worries Linger Over USMCA Review
Despite the upbeat GDP numbers, a cloud of uncertainty hangs over the Canadian market. The United States-Mexico-Canada Agreement (USMCA) is set to undergo a formal review process, which could lead to renegotiations or even a wind-down of the trade pact. The USMCA, which replaced NAFTA in 2020, is a cornerstone of North American trade, and any disruption could hit Canadian exporters hard.
Trade-sensitive sectors like energy, manufacturing, and agriculture are particularly exposed. The TSX has a heavy weighting in energy and materials, making it more vulnerable to trade shocks than the more tech-heavy S&P 500. That structural difference helps explain why the Canadian index has lagged its U.S. counterpart this quarter.
Investors are watching for any signals from Ottawa and Washington about the review process. A smooth renegotiation could remove a key overhang, while a breakdown could trigger a selloff in Canadian stocks.
What It Means for Investors
The TSX's eight-quarter winning streak is impressive by historical standards — the last time the index achieved such a run was in 1996. But the gap between Canadian and U.S. returns is a reminder that not all markets move in lockstep.
For everyday investors, the divergence highlights the importance of diversification. While the S&P 500 has been propelled by a handful of mega-cap tech stocks — a trend also seen in European markets, as noted in our coverage of the STOXX 600's 10% quarterly surge — the TSX offers exposure to different sectors, including financials, energy, and materials. That can provide a buffer when U.S. tech stocks stumble, but it can also mean missing out on big rallies.
The Canadian market's relative underperformance this quarter is not necessarily a sign of weakness. The TSX's gains have been steady and broad-based, rather than driven by a narrow group of stocks. That kind of resilience can be attractive for investors seeking less volatility.
However, the trade uncertainty around the USMCA is a real risk. If tariffs or trade barriers increase, Canadian companies — especially in commodities and manufacturing — could face headwinds. On the flip side, a resolution could unlock further gains.
Investors should also keep an eye on the Bank of Canada's next moves. With GDP beating expectations, the central bank may feel less pressure to cut interest rates, which could support the Canadian dollar but also keep borrowing costs higher for longer.
Looking Ahead
The third quarter will bring new challenges and opportunities. The USMCA review process is likely to dominate headlines, along with global economic data and central bank policy decisions. For now, the TSX's streak is intact, but the gap with the U.S. market is a reminder that Canada's market dances to its own tune.
