* Toronto stocks retreat from record high
* Materials and energy shares lead decline

The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 79.17 points, or 0.5 percent, at 14,586.90 at midmorning. Earlier in the session it fell as low as 14,553.06.
On Monday the index ended up 144.88 points at a new closing high of 14,666.07 after reaching a record high of 14,695.75.
