My other half reported to T4 at 1105 for a 1235 dep for YYZ....he arrived back home last nite at 2000 after a day spent sitting around waiting for info. He was reduced to calling ops via his mobile phone from the flt deck as there was just no reply to his radio calls....sorry story of no de icing avbl, followed by cabin crew going out of hours. This was the second day the YYZ had been scrubbed too! Apparently the police were called to gate when pax were told of furthur delay! Flt eventually left at 2343.....
