No reason for the agent to be snarky. But I do have to agree that keeping benefits of various credit cards straight must be a nightmare for the agents at Air Canada.

Personally, I wouldn't call TD direct - maybe TD for Aeroplan - and hope for a straight answer.

Re Priority Boarding, if everyone with TD Infinite and CIBC Aerogold cards has access to priority boarding on AC reward tickets the line-up could be long.

Also, what if a passenger books an Aeroplan reward ticket but charges the taxes to Amex - but also holds a CIBC Aerogold (as in my husband and I) or/and a TD Aeroplan Infinite cards? The agent is not about to start looking at payment info on the e-ticket and it is unlikely that AC is going to change its boarding pass technology to reflect a free checked bag or priority boarding. So I would have to go with if it is a reward booking on AC - then the passenger is entitled to check a free bag - after a "discussion".

Our CIBC Aerogold cards have been sold to TD. Since renewal date for the CIBC card is Nov., we will receive the TD cards prior to that. So, I looked at the card picture on the CIBC website - the new card appears to look exactly like the old one (except expiry date would be much later). So I would have to assume that showing the old CIBC Aerogold card to the agent would work for the free bag? (I will be checking this by the way.)
