His passport has been revoked by Turkey and believe Turkey has filed an Interpol red slip on him which is supposed to get him arrested per a complicated web of international treaties so Turkey can make the case to extradite him. He has charges pending I believe within Turkey?
Political dissent is largely criminalized in Turkey, especially if you personally criticize Erogen.
I don't think its publicly known if he's able to travel to Canada, because we don't know what their government and legal system will do about the situation. Its unlikely he would be extradited to Turkey, but he could easily be refused entry to Canada as he lacks travel documents.
