I would have thought the OP would have already done the homework on the CIBC online site as a prerequisite, but for what it is worth, CIBC has an excellent 8 part FAQ style explanation and a relevant response to one of those parts says

Which financial institutions participate in the INTERAC e-Transfer service?

Rate this response
The following financial institutions participate in the INTERAC e-TransferTM service:

CIBC
Bank of Montreal
Scotiabank
TD Canada Trust
Royal Bank of Canada
Participating financial institutions offer their Online Banking customers the ability to send INTERAC e-TransferTM and to receive them quickly.

Customers at non-participating Canadian financial institutions cannot send INTERAC e-TransferTM and cannot use Online Banking to receive them; however, they can receive and deposit the transfers using the CertaPay process.
