TORONTO -- Omar Khadr should be monitored with electronic bracelets when he's released from prison, says a Scarborough group that want him charged with treason.

Shobie Kapoor of Canadian Patriotic Society -- a grassroots citizens' group -- insisted Sunday that Khadr will be used by Islamic extremists as a "propaganda machine on the GTA mosque circuit."

She said Khadr, 26, can also be used to raise funds and recruits at Toronto-area mosques when he's freed.

"He will draw out all the jihadis," Kapoor said. "They will all pay big money to see him."

Her group gave Scarborough Centre MP Roxanne Jame a 100-name petition calling for Khadr to be charged with treason. The Conservative MP is expected to pass it along this week to Public Safety Minister Vic Toews.

Khadr was seven weeks shy of his 16th birthday when he tossed the handgrenade that killed a U.S. army medic during a firefight in Afghanistan.

His sympathizers argue he should receive clemency, painting him as a child soldier who fell in with the wrong crowd. Others argue he's loyal to al-Qaida and will return to the frontlines of terrorism if given the chance.

Khadr is serving the remainder of an eight-year sentence at Millhaven Institution near Kingston, Ont., after being transferred to Canada from a military cell in Guantanamo Bay, Cuba, on Sept. 29. He is eligible for parole in 2013.

"This man is dangerous and has to be monitored whenever he is freed," Kapoor said. "He will be a lightning rod for other jihadis."

Kapoor said Khadr sympathizers are already aligning themselves to be at his side after his release.

"The Government of Canada is requested to try Omar Khadr for treason under the laws of Canada for his actions against coalition forces in Afghanistan," states her group's petition.

There have been several demonstrations in front of the home of his sister and other family members by protesters who want to keep Khadr out of Scarborough, in east Toronto, where he grew up.
