The former head of Jitec Inc. was convicted yesterday of insider trading and deceiving investors while pumping up the value of his now-defunct Montreal high-tech firm. A judge found Benoit Laliberte, 35, guilty on 41 of 48 counts of breaking Quebec's securities laws. Quebec's securities regulator will seek about $1.5-million in fines plus costs from Laliberte for manipulating share prices while the company was listed on the Montreal Stock Exchange. Thirty of the convictions were for failing to disclose changes in Laliberte's control over Jitec shares. The rest of the counts were for insider trading, deceiving investors in news releases and inflating the value of contracts.
