Crown prosecutors began presenting evidence Friday in the trial of one of 11 suspects charged in the alleged Toronto bomb plot.

While the trial opened in Brampton, Ont., in March, Friday was the first day the Crown presented evidence in the case.

The 20-year-old on trial is accused of being part of a homegrown terror cell — one of 18 men and teenagers arrested two years ago during dramatic raids around Toronto. He was charged as a youth and cannot be identified under the Youth Criminal Justice Act.

Since the initial arrests, the Crown has dropped or stayed charges against seven of them.

The first witness called by the Crown was a member of the Integrated National Security Enforcement Team. RCMP Cpl. John Mecher testified about evidence police seized during the investigation, dubbed "Project Osage," that led to the massive sweep.

Mecher, who is in charge of securing and tracking evidence in the case, told Ontario Superior Court that investigators recovered spent shell casings and a bullet-riddled tree trunk at or near an alleged extremist training camp north of Toronto.

Police seized other items from the home of one of the adult suspects, included a bomb-making manual, a video showing a small explosive being detonated by cellphone and a collection of cellphones and circuit boards, the court heard.

Other evidence presented included a Crazy Carpet-type toboggan, which prosecutors allege was part of an obstacle course used at a training camp.

Defence lawyer Mitchell Chernovsky said to Mecher that while the alleged plot involved attacks on power grids, Canada's spy agency, the CBC, the RCMP and the nuclear power plant in Pickering, Ont., no warnings were ever issued to them.

"I suggest these people weren't notified because the plan was always a fantasy," Chernovsky said, adding talk of importing high-powered rifles was simply boasting among the men.

Chernovsky also ridiculed suggestions the group was intent on attacking Canada.

"You seized one 9 mm gun?" Chernovsky asked.

Mecher agreed that was the extent of the weaponry.

The suspect on trial, who in the past converted to Islam from Hindusim, sat quietly, taking notes. Earlier this month, he stood up in court, fired his lawyer and declared he only respected Islamic Sharia law. Days later, he reversed his decision and rehired his lawyer.

The suspect is the only one remaining of four people charged as youths in the case. The trials of the other adults could take years to come to court.
