It seems that you can only make Hertz reservations on the web site now. I sent an e-mail to AC, and this is their response. The only reason I use ac.com was for the 100 mile booking bonus.

Dear Ms. MG:
Thank you for your email and your patience in awaiting our reply.
As with most companies, Air Canada periodically reviews its services to ensure that our product offering is responding to customer demand.
While Hertz is now our dedicated on-line service provider for car rentals, your preference is appreciated and we have brought your comments to the attention of the appropriate operational department for future consideration.
Thank you again for sharing your comments. We hope there will be a future opportunity for you to explore the advantages we feel this new service provides.
Sincerely,
RC
Customer Relations

My company requires that all car reservations be made with Avis. How do I bypass Hertz to make an Avis reservation on your website?
