The Toronto Stock Exchange fell on Monday, snapping its five-day winning streak, as investors were jittery after U.S. President Donald Trump's scathing attack on Federal Reserve Chair Jerome Powell for not cutting interest rates.

In commodities, gold prices continued their record run and briefly broke above $3,500 per ounce to an all-time high on Tuesday.

Oil prices also rose as investors took advantage of the previous day's losses to cover short positions.
