(Reuters) -Canada's main stock index fell on Tuesday by the most in nearly six weeks as commodity prices fell and investors grew more worried about the health of the U.S. regional banking sector.
The Toronto Stock Exchange's S&P/TSX composite index ended down 236.87 points, or 1.2%, at 20,439.87, its biggest decline since March 15, preliminary data showed.
U.S. stocks also fell as the quarterly results of some companies raised concerns about a slowing U.S. economy and First Republic Bank (NYSE:FRC) disclosed it lost more than half its deposits during last month's banking crisis.
The Toronto market's financials sector, which accounts for 28% of the index's weighting, fell 1.7%. Energy lost 2% as oil settled 2.2% lower at $77.07 a barrel.
Utilities was the only major sector to end higher, gaining 0.3%.
