However, current customers of CIBC Aerogold Visa cards won't initially see any change and the companies are saying it won't be until mid-2014 until the transition is completed.
Under an interim agreement between the two banks, CIBC will continue to process the accounts until new TD cards are issued to about half a million affected customers.
The trio of companies announced Friday that they have completed a previously announced deal that enables CIBC to retain about half of its porfolio of Aeroplan customers.
TD becomes the primary issuer of new Aeroplan Visa cards for the next 10 years, and it will acquire the half of the CIBC Aerogold customer base that doesn't have broader banking relationships.
"The successful completion of this transaction puts Aimia in a unique place, working alongside strong financial services partners and Air Canada to shape what the future can look like for coalition loyalty," said Rupert Duchesne, group chief executive for Aimia.
"The increased engagement of our members and our partners as we introduce a market leading program will be at the heart of what will drive our growth."
Aimia had originally decided to switch its allegiance to TD Bank from CIBC at the end of its latest 10-year agreement, which expires on Dec. 31.
However, CIBC protested and eventually the three companies arrived at a compromise, announced in September — three weeks after the first deal was announced on Aug. 26.
A total of $312.5 million, plus the value of related outstanding card receivables, will be paid to CIBC, including $150 million from Montreal-based Aimia.
Aimia said Friday that current CIBC Aerogold Visa cardholders will receive a letter from the bank in January informing them whether their account will stay where it is or transition to TD in mid-2014.
Cardholders with accounts moving to TD will also receive a letter from TD in January providing them with more information about the transition.
As of Dec. 27, TD is acquiring about 550,000 accounts representing $19 billion of annual retail spending and $3.3 billion of credit card receivables outstanding, which is the amount the consumers owe.
It's a significant move for TD, which had lagged CIBC and RBC (TSX:RY) in offering credit cards that reward shoppers with points that can be exchanged for airline tickets and other goods or services.
"We're excited about this opportunity to enhance our offering to customers and grow our leadership in credit cards," said Michael Rhodes, TD's executive vice-presiden for North American credit cards and merchant services.
"We're thrilled to offer TD customers an outstanding suite of Aeroplan Visa credit cards in January 2014, and we look forward to welcoming CIBC Aerogold customers making the transition to TD in mid-2014."
TD said Friday it will pay $162.5 million to CIBC, including $50 million for the CIBC Aeroplan accounts, plus a commercial subsidy of $112.5 million plus HST over three years.
