Canada’s stock market delivered one of its strongest performances of 2026 on November 4, but the celebration was far from universal. The S&P/TSX Composite Index surged 809.12 points, or 2.28%, as investors responded to the Democrats’ sweeping victory in the U.S. midterm elections. Meanwhile, Canadian energy stocks plunged 6.2%, reflecting a dramatic decline in oil prices and changing expectations surrounding the conflict with Iran.
The contrasting movements highlighted the complicated relationship between politics, commodity prices, and investor confidence. Financial institutions and mining companies benefited from renewed optimism, while oil producers faced significant selling pressure. For Canadian investors, the session offered a striking reminder that political developments can create winners and losers within the same market, even when the broader economic outlook appears to improve.
TSX Records Its Biggest Daily Gain in Seven Months
The S&P/TSX Composite Index finished Wednesday, November 4, at 36,341.40 points, representing an increase of 809.12 points from the previous session’s close of 35,532.28. The 2.28% advance marked the benchmark’s strongest daily percentage performance since March 31, 2026, and its highest closing level since September 4. The surge was particularly notable because Canadian equities had struggled in the preceding sessions. On November 3, the index had declined 0.75%, reflecting the uncertainty surrounding the American election and the outlook for international markets.
Wednesday’s recovery demonstrated how quickly investor sentiment can change when major political uncertainties begin to clear. The index opened at 35,879.03 before advancing throughout the trading day, reaching an intraday high of 36,417.13. For Canadians holding diversified retirement portfolios, pension investments, or equity funds, the movement represented a substantial single-day improvement in market values. However, the headline gain concealed significant differences among industries, with strong performances in banking and mining offsetting sharp losses among energy producers.
Democratic Election Victory Sparks a Relief Rally
The immediate catalyst for the Canadian market’s advance was the outcome of the November 3 U.S. midterm elections, which saw Democrats secure control of both the House of Representatives and Senate. The results represented a major political setback for President Donald Trump, creating expectations that his administration would face stronger congressional opposition during the final two years of his presidency. Investors interpreted the outcome as a potential constraint on disruptive policy changes, particularly those involving trade, government spending, and international conflicts.
Philip Petursson, chief investment strategist at IG Wealth Management, described the market reaction as a relief rally extending beyond American equities. The prospect of additional checks on presidential power encouraged speculation that trade tensions could eventually ease. For Canadian businesses dependent on access to the American market, even the possibility of greater policy stability was encouraging. Nevertheless, Democratic control of Congress does not automatically reverse existing tariffs or eliminate uncertainty. Trump retains substantial executive authority, meaning significant negotiations and political disagreements could continue despite the election results.
Financial Stocks Become the Biggest Support for the Rally
Canadian financial stocks emerged as a major source of strength during Wednesday’s session, with the TSX financial sector advancing approximately 3.1%. The gains mattered because financial companies represented roughly 35.1% of the benchmark index at the end of October, according to S&P Dow Jones Indices. Large institutions such as Royal Bank of Canada, Toronto-Dominion Bank, and Bank of Montreal carry considerable influence over the market’s overall direction. Bank of Montreal shares, for example, finished November 4 at $247.61, a daily increase of approximately 2.9%. The broader financial rally reflected investors’ willingness to reconsider economic risks as the political outlook in Washington shifted.
One particularly notable performer was Fairfax Financial Holdings, whose shares climbed approximately 10.7%. The insurance company had reported third-quarter net earnings attributable to shareholders of US$929.6 million, below the US$1.15 billion recorded a year earlier, but its underlying insurance operations demonstrated resilience. Adjusted operating income from property and casualty insurance and reinsurance increased to US$1.375 billion. Fairfax’s performance illustrated how investors can reward strong operating fundamentals even when headline profit declines. For Canadian financial institutions, the bigger question remains whether improved market confidence will translate into stronger lending, investment activity, and economic growth.
Gold and Mining Stocks Deliver Another Major Boost
While energy producers struggled, Canadian mining companies benefited from a powerful rebound in precious metals. The TSX materials sector advanced approximately 7.3%, making it one of the strongest contributors to the broader market’s recovery. Gold prices rose sharply as the U.S. dollar weakened after the election, with spot bullion climbing roughly 3.4% to around US$4,060 per ounce. Because gold is internationally priced in American dollars, a weaker U.S. currency can make the metal more attractive to overseas buyers. Canadian gold producers consequently found themselves benefiting from a combination of stronger commodity prices and renewed investor demand.
The importance of this movement extended beyond individual mining companies. Materials represented approximately 15.8% of the S&P/TSX Composite Index at the end of October, giving the sector considerable influence over Canadian market performance. Mining stocks can respond strongly to changes in commodity prices because higher selling prices may improve earnings expectations without requiring an equivalent increase in production. However, the relationship also works in reverse when bullion prices decline. Wednesday’s rally therefore underscored both the opportunity and volatility associated with Canada’s significant exposure to resource companies. It also demonstrated that political uncertainty can benefit some commodities while putting intense downward pressure on others.
Oil Prices Collapse as Investors Reassess the Iran War
The most dramatic commodity-market development came from crude oil, which suffered one of its sharpest daily declines in months. U.S. West Texas Intermediate futures fell US$7.97, or 8.3%, to settle at US$88.12 per barrel. Brent crude, the international benchmark, declined US$8.98, or 8.7%, to US$94.62. Both benchmarks closed at their lowest levels since August 31. The selloff followed growing expectations that the Democratic victory could increase political pressure on President Trump to pursue negotiations rather than further escalation in the U.S.-Israeli conflict with Iran.
The market reaction reflected how much geopolitical uncertainty had become embedded in oil prices. Fighting in the Middle East had raised concerns about production, transportation, and shipping through strategically important waterways, increasing the premium traders were willing to pay for crude. President Trump acknowledged that the Iran war had contributed to Republican election losses, encouraging speculation that Washington might reconsider its military approach. For energy traders, the prospect of reduced conflict raised expectations of fewer supply disruptions. However, a diplomatic settlement remained uncertain, and renewed hostilities could reverse the price movement. Wednesday’s decline represented a rapid change in expectations rather than confirmation that the conflict was ending.
Canadian Energy Stocks Fall 6.2% Despite the Broader Market Surge
Canada’s energy sector absorbed the direct consequences of collapsing crude prices, declining approximately 6.2% even as the overall TSX advanced more than 2%. Energy was one of only two major Canadian market sectors to finish Wednesday lower, alongside health care. The contrast was particularly striking because energy companies accounted for approximately 17.5% of the S&P/TSX Composite Index at the end of October. Major producers and pipeline operators form an important part of Canada’s stock market, meaning substantial movements in their share prices can significantly influence the performance of diversified investment funds.
For oil producers, an abrupt reduction in crude prices can quickly change expectations for future revenue and cash flow. Companies with substantial production volumes may experience particularly pronounced market reactions when investors reassess the value of their output. Wednesday’s decline did not necessarily indicate that energy companies had suddenly become financially weaker overnight. Instead, investors were adjusting valuations to reflect a different outlook for oil prices. The market’s ability to gain 809 points despite this weakness demonstrated how powerful the advances in financial and materials stocks had become. It also revealed why a rising benchmark does not guarantee positive returns across every industry.
Cenovus Shares Plunge Despite Record Production and Higher Profits
Cenovus Energy provided one of the clearest examples of how difficult Wednesday’s trading environment became for Canadian oil producers. The Calgary-based company reported third-quarter net earnings of approximately $3.36 billion, up from $1.29 billion during the same period in 2025. Its upstream production reached a company record of roughly 1.024 million barrels of oil equivalent per day, while improved refining performance supported stronger operating results. Despite those achievements, Cenovus shares finished approximately 7.8% lower as investors responded to the sudden collapse in global oil prices.
The disconnect between operating performance and stock-market returns illustrated the forward-looking nature of equity valuations. Cenovus generated approximately $5 billion in adjusted funds flow and $3.6 billion in free funds flow during the quarter, demonstrating substantial cash-generating capacity. However, the company also faces uncertainty surrounding Canadian crude pricing, including the discount at which Western Canadian Select trades compared with West Texas Intermediate. That differential had widened to more than US$30 per barrel, creating an additional challenge for producers. Although Cenovus management expected the weakness to be temporary, Wednesday’s market reaction showed that strong quarterly earnings alone could not protect energy stocks from deteriorating commodity-price expectations.
U.S. Stock Markets Experience Their Own Post-Election Surge
The Canadian rally unfolded alongside substantial gains across Wall Street, reinforcing the international nature of the market reaction. The Dow Jones Industrial Average jumped 1,569.40 points, or approximately 3%, closing at 53,356.12. The S&P 500 advanced 1.6% to 7,688.62, while the Nasdaq Composite increased 1.4% to 25,736.51. American investors appeared encouraged by expectations that divided government could reduce the likelihood of dramatic legislative changes. Falling oil prices also helped ease some inflation concerns, contributing to lower U.S. Treasury yields and improving sentiment toward equities.
However, American investors were just as selective as their Canadian counterparts. Hospital operators and retailers serving lower-income consumers performed strongly amid expectations that Democratic lawmakers could pursue different health-care and household assistance policies. Meanwhile, energy companies, certain technology businesses, and defence contractors faced selling pressure. Concerns about tighter regulation also weighed on some artificial-intelligence infrastructure companies. The contrasting performances demonstrated that the election was not universally positive for corporate earnings expectations. Instead, investors were reassessing which industries might benefit or suffer under a Democratic-controlled Congress and a Republican president, with the resulting changes extending across North American financial markets.
Canadian Dollar Strengthens as New Trade Data Adds Another Dimension
The Canadian dollar also benefited from Wednesday’s changing market environment, strengthening to approximately 71.61 U.S. cents during the session and reaching its highest intraday level in seven weeks. The improvement came despite falling oil prices, which can otherwise create downward pressure on Canada’s currency. A broadly weaker U.S. dollar and stronger Canadian trade figures helped support the loonie. Statistics Canada reported that Canada’s merchandise trade surplus widened to $5.4 billion in September, compared with a revised $5.0 billion in August. Exports increased 0.2%, while imports declined 0.3%.
The underlying trade figures were more complicated than the headline surplus suggested. Statistics Canada reported that higher crude oil and gold exports helped support the monthly improvement, while merchandise export volumes actually fell 4%. Exports declined across eight of the eleven major product categories, illustrating uneven economic conditions beneath the stronger overall trade balance. The distinction is particularly important because September’s figures reflected an earlier period of relatively elevated commodity prices, not Wednesday’s abrupt oil selloff. For Canadian businesses, the stronger dollar could reduce some U.S.-dollar purchasing costs, but it could also make certain exports less competitively priced. These competing effects reinforced the uncertainty surrounding Canada’s economic outlook.
Ottawa Maintains Its Trade Strategy as Investors Look Beyond the Rally
Despite the enthusiasm surrounding the Democratic victory, the Canadian government signalled that its approach to trade negotiations with Washington would remain unchanged. Canada-U.S. Trade Minister Dominic LeBlanc said the election results would not significantly alter Ottawa’s priorities or ongoing work with American officials. He also indicated plans to speak with U.S. Commerce Secretary Howard Lutnick and Trade Representative Jamieson Greer. Prime Minister Mark Carney had acknowledged that progress was being made in discussions, but emphasized that unresolved issues remained. The government’s response reflected an important distinction between improved market sentiment and actual changes in trade policy.
The uncertainty surrounding the Canada-United States-Mexico Agreement remains particularly significant. During the agreement’s July 2026 joint review, the United States declined to extend it in its existing form, triggering annual reviews rather than an immediate termination. CUSMA remains in force, with its current term extending to 2036 unless the parties reach an agreement on renewal or changes. For Canadian manufacturers, exporters, energy producers, and investors, negotiations will remain a major consideration through 2027. Wednesday’s 809-point rally demonstrated how strongly markets can respond to expectations of greater stability. Whether that optimism produces lasting gains will depend on tangible developments in trade relations, corporate profitability, geopolitical tensions, and commodity markets.
