Bumping....

My folks in Toronto need a new mileage card - I am pretty clueless about the programs in Canada, so I'm not sure where to steer them, and after checking the various bank websites, I'm even more confused....

So - this is what I've figured out. They want a Visa (or MC) card, but they have an existing Amex card. After checking CIBC and Amex, it looks like they could apply for the CIBC Aerogold Visa Infinite card and also convert their plain Amex to the Aeroplan Plus Gold.

Their bonus Aeroplan miles in the first year should be 15,000 (CIBC) + 25,000 (Amex), and they will earn 1/1 from Visa for everyday purchases, 2/1 at gas stations, and the Amex card will give them 1.25/1 on everything after they pass 10K in spend.

So my questions are thus:

1) Is this combination the best available program in Canada?

2) Can they have miles from the Visa card and Amex card go into the same Aeroplan account? Or will they need two different Aeroplan accounts?
Editing to add: they can get both credit cards in the same name as the Aeroplan account
