A 22-year-old man who admitted he was part of a Toronto-based group that was planning a terrorist attack in the city will find out on Jan. 18 what price he must pay for his role in the plot.

Saad Gaya, a member of the "Toronto 18," was supposed to be sentenced on Wednesday but a Brampton, Ont. judge decided to delay the sentencing hearing.

The former McMaster University student will now be sentenced the same day as 24-year-old Zakaria Amara, the gang's leader who also pleaded guilty to the crime.

Gaya has already publicly apologized for his role in the terror plot which called for truck bombs to be blown up. He pleaded guilty in September, 2009.

The Crown has said it will seek a prison sentence of up to 18 years because Gaya was a willing participant.

Gaya called it a "shameful crime" but insisted he did not know that the targets were to be the Toronto Stock Exchange and the offices of CSIS, Canada's intelligence agency, both located in the heart of Canada's biggest city.

The man also told courtroom in December that he was "politically na�ve" for believing that the plan would help convince Canadian officials to withdraw their troops from Afghanistan.

Gaya's attorneys are arguing for a sentence in the range of 9 to 15 years.

Police arrested Gaya in June 2006, as he was unloading a truck that was filled with three tonnes of bags marked ammonium nitrate fertilizer - an ingredient often used to make bombs.

The amount of fertilizer that was discovered is three times that of what was used in the 1995 Oklahoma City bombing -- an incident that saw 168 people killed.

Gaya is the latest "Toronto 18" member to plead guilty in the case.

Ali Dirie, 26, was sentenced to a maximum of 10 years in prison after pleading guilty to participating in a terrorist group. He admitted he procured weapons, arranged false travel documents and tried to recruit extremists for a domestic terrorist.

Saad Khalid, 23, was given a 14-year sentence after he admitted to conspiring to commit terrorism.

So far, only one accused in the Toronto 18 terror case has gone to trial. That case resulted in a conviction.

Nishanthan Yogakrishnan, 21, was found guilty of participating in, and contributing to, a terrorist group.

Although he was 17 years old at the time of the crimes and was tried as a youth, Yogakrishnan received an adult sentence of 2 � years. He was released in May after being credited for time served before trail.

Seven others accused members of the Toronto 18, including the alleged ringleaders, remain in custody and are awaiting trial.

Seven of the 18 men and youths arrested have since had their charges dropped or stayed.
