* TSX down 360.4 points, or 3 percent, at 11,641.84
* All of the TSX's 10 main groups fall
TORONTO, Jan 20 (Reuters) - Canada's main stock index
slumped 3 percent on Wednesday, hitting an almost 3-1/2 year
low, with energy and financial shares leading the drop as a rout
in oil prices and global equity markets rumbled on.
Investors failed to take much comfort from the Bank of
Canada holding rates steady rather than cutting despite lower
growth, opting for patience because of expected help from a weak
currency, past rate cuts, fiscal stimulus and U.S. strength.
At 10:27 a.m. EST (1527 GMT), the Toronto Stock Exchange's
S&P/TSX composite index .GSPTSE was down 360.4 points, or 3
percent, at 11,641.84.
All 10 main groups fell, with a 5.8-percent plunge in energy
stocks helping push the index to its lowest level since August
3, 2012.
Suncor Energy Inc SU.TO fell 5.4 percent to C$27.52 and
Canadian Natural Resources CNQ.TO declined 6.6 percent to
C$21.41.
U.S. crude touched its lowest since 2003, as a global supply
glut bumped up against bearish financial news that sparked
deeper worries over demand.
Banks and other financial stocks also weighed, with Royal
Bank of Canada RY.TO down 3 percent to C$65.41 and Bank of
Nova Scotia BNS.TO off 3 percent at C$51.66. Insurer Manulife
Financial Corp MFC.TO fell 3.8 percent to C$17.35.
Telecoms slumped 5.9 percent, while industrial stocks fell
1.5 percent.
There were 10 decliners for every rising stock, and 83
issues were at new 52-week lows.
