Saudi Arabia's Foreign Minister Adel bin Ahmed Al-Jubeir speaks during the second day of the dialogue.
Trudeau said he might cut off any arms export permits that allow Canadian manufacturers of military equipment to ship their goods to Saudi Arabia.
The Saudi foreign minister said that his country still saw the principles of the Beirut conference in 2002 that calls for Israel to withdraw from occupied Palestinian territory and allow a Palestinian state within 1967 borders with East Jerusalem as the capital as the pre-requisite in order for peace and normalized ties.
A vigil is held for Jamal Khashoggi in Istanbul, as pressure is piled on the Saudis over his killing.
Hatice Cengiz, in an interview with Turkish broadcaster Haberturk, said Khashoggi had not wanted to go to the Saudi consulate, where he was killed shortly after entering it on October 2.
Khashoggi's killing has severely damaged the heir to the throne, who many believe must at a minimum have been aware of the Saudi operation, which involved several members of his personal guard and other senior officials.
The German leader said she was prepared to take "appropriate measures together with global partners" following the killing.
At a conference in Riyadh on Wednesday, the crown prince said the killing was a "heinous crime that can not be justified" and warned against any efforts to "manipulate" the crisis and drive a wedge between Saudi Arabia and Turkey, which are regional rivals but also diplomatic and business partners.
Glasgow's website states: "The university has a long-established relationship with Saudi Arabia and we have been welcoming students here for many decades".
"You see, an important Saudi official uses an expression ... and we say it's now evident that he is killed, but where is it (the body)?"
Meanwhile, the Kremlin said Russian Federation believes that the Saudi royals were not involved in the murder.
"You need to show this body", Erdogan insisted on Friday, indicating that his country had more evidence about the killing to reveal.
Saudi Crown Prince Mohamed bin Salman then denounced the "heinous crime", and the nation's public prosecutor then conceded the murder was "premeditated".
Khashoggi's fiancée also mentioned that no one from the Saudi Arabian government called her following Khashoggi's death.
In particular the Washington Post, Khashoggi's former employer, has criticised the Saudi response in numerous fiery editorials.
