Saudi Canadian relations (Jeddah)

Dears all,
I keep hear "Rumors" that Saudi Arabia is about to ban Canadians from working, staying or even visiting Saudi Arabia since Canada is causing trouble to Saudi Students applying for continuing their studies in Canada and after researching the net I found other reason provoking strains in relations represented in a TV add related to Saudi Crude Oil and women rights. U can see add on the following LINK: Protected content
or U can search "Ethical Oil TV Ad - Saudi Arabia"
Does anyone know the truth? Some Canadians in an International company working in eastern region of KSA are on a visit visa and they were asked to leave. I don't know what would happen to canadians with IQAMA are they going to be denied a renewal for their IQAMAS ???
