Riyadh also said it will relocate thousands of Saudi students studying in Canada to other countries, while state airline Saudia (also known as Saudi Arabian Airlines) announced it was suspending flights to Toronto.
Further straining ties, the Saudi central bank has instructed its overseas asset managers to dispose of their Canadian equities, bonds and cash holdings "no matter the cost", the Financial Times reported today.
Canada sparked fury in Riyadh last week when it called for the "immediate release" of rights campaigners, including award-winning women's rights activist Samar Badawi, the sister of jailed blogger Raif Badawi.
It came after more than a dozen women's rights campaigners were detained and accused of undermining national security and collaborating with enemies of the state. When asked about the jailed activists, Jubeir reiterated the government's earlier stance that they had been in contact with foreign entities, but did not specify the charges against them.
"The matter is not about human rights, it is a matter of national security," Jubeir said, referring to the row with Canada.
"Saudi Arabia does not interfere in the affairs of Canada in any way. Therefore, Canada must correct its actions towards the kingdom."
Canada has indicated it will not back down, despite the risk of imperilling business deals including a USD 15 billion agreement to sell Riyadh light armoured vehicles.
If the deal is scrapped, thousands of jobs could be lost in Canada, experts say.
