The TSX composite closed Monday at a record 36,468.33, up 0.21 percent, as energy names led a session where 511 stocks advanced against 459 decliners. Brent crude pushed toward $88 during the session on renewed Strait of Hormuz uncertainty, and by Tuesday morning it had extended to $89.76, up a further 2.3 percent, after President Trump demanded compensation from Iran as a condition for resuming talks.

Strathcona Resources led every name on the index, up 8.74 percent to $42.04. International Petroleum Corp added 8.24 percent to $33.10, and Endeavour Silver rose 7.30 percent to $14.26. All three moves trace directly to the same oil price strength driving the broader energy sector.

Where the Session's Losses Came From

Superior Plus was the day's worst performer, down 9.02 percent to $7.46. ATS Corporation fell 6.81 percent to $27.51. Barrick Mining rounded out the bottom three, down 6.45 percent to $57.03 after missing its earnings per share estimate by two cents despite gold production beating guidance and net earnings rising 50 percent from a year earlier.

None of the session's three worst performers were connected to each other or to the broader oil-driven move higher. Each fell on a distinct company-specific catalyst, which is the read that matters here: Monday's decliners were idiosyncratic, not a sector-wide or index-wide signal.

What the Standout Movers Chart Shows

The gap between Monday's best and worst single-session performers spans nearly 18 percentage points, and the pattern splits cleanly along commodity lines rather than broad market sentiment.

Strathcona Resources and International Petroleum Corp led on rising crude. Barrick, ATS and Superior Plus were the session's worst performers on company-specific earnings news unrelated to the broader energy move.

The Currency and Rate Backdrop

USD/CAD fell to 1.3929 Monday, an eight-week high for the Canadian dollar, driven by the gap between Canada's blowout July jobs report and a weak US payrolls print released the same Friday. Canada's 10-year government bond yield climbed to 3.67 percent, its highest level since May, as strong domestic data collided with rising oil prices to complicate the inflation picture heading into the Bank of Canada's September 2 decision.

Gold traded near $4,391 an ounce Monday, essentially flat on the session and near its highest opening level since early June, even as gold mining names diverged sharply on individual earnings results rather than moving with the metal itself.

What to Watch Wednesday

The US Consumer Price Index for July releases Wednesday at 8:30 a.m. Eastern, the single data point most likely to move both the Fed's rate path and the currency and bond market backdrop this week. Combined with oil's continued climb Tuesday morning, it sets up a session where inflation data and geopolitical risk are pulling on Canadian markets from two different directions simultaneously.
