If you pay annually all Autoplan brokers will accept Amex (and others) for ICBC insurance. Monthly payments only available via CTFS's bill payment interface. I've timed my Amex Business Gold app to coincide with renewal to knock a big chunk out

Some automakers financing arms are also on CTFS (Ford is for sure, Subaru and Toyota were not when I checked) so you could earn 1% back on Ford payments
