Thanks to DomainNameWire.com for their post today stating that the domain CreditCards.ca has been acquired by financial media company Bankrate. They also said the transaction likely took place last December.
I don't think many in the .ca community knew about this transaction, and it hasn't been reported anywhere else to my knowledge. Likely this was an NDA sale and the details will never be known.
Bankrate also operates CreditCards.com, and this is a good example of a company buying the .ca domain of their market to get a foothold in Canada. Owning CreditCards.ca makes them look like the expert on credit cards in Canada.
Although this was reported elsewhere, I still like to post about a premium .ca sale like this in my blog for those who may not have seen the news.
