Canada's Big Six banks face a high bar ahead of their third-quarter earnings releases. Third-quarter earnings for Canada's Big Six lenders are set to be released over three days this week, beginning with numbers Tuesday from Bank of Montreal and Bank of Nova Scotia. Analysts broadly anticipate a continuation of recent trends, with growth driven by capital markets activity, wealth segment revenue, and credit losses held in check.

However, tailwinds have pushed shares higher, raising questions about whether results can sustain stock prices. Paul Holden, an analyst at CIBC Capital Markets, forecasts banks' results will look similar to last quarter, with rising investment banking and trading revenue, improving commercial loan growth, and signs credit losses won't be a concern. Based on Fact Set data, adjusted per-share earnings for the large banks are expected to jump 28% from a year earlier and top-line revenue 22%.

Share prices are up an average 26% so far in 2026, while the Toronto market is up 16%. Even with banks trading at premium valuations, Bof A Securities argued investors should maintain exposure to what its analysts say is a Canada story underpinned by the improving domestic outlook under Prime Minister Mark Carney and a banking sector well positioned to convert that into higher returns. The outlook isn't without clouds, largely due to the recent breakdown in bilateral trade talks between Ottawa and Washington and an escalation of tariffs.

Tim O'Brien, managing director for North American financial institution ratings at Morningstar DBRS, noted banks' AA-range credit ratings reflect superior underlying credit profiles well-positioned to deal with any further near-term deterioration in the credit environment.
