I am a commuter out of YYZ... United agents are terrible. Every single occasion they have no clue on how to list me at the ticket counter... For this matter 75% of the time ORD agents, when trying to get listed to YYZ, are just as terrible.
The only way I have found to get listed is using the id90 website and paying a zed fare, normally $80 instead of the normal $60 in taxes only. It is frustrating and I have never managed to get them to figure out how to list a jumpseater.
