If you're referring to Aeroplan, the only other good 'free' offer (for one year) is the Amex Gold Rewards MR charge card. It offers 25,000 Membership Rewards (MR) welcome bonus, after $500 spending in 3 months, waived first year fees. The MR points convert 1:1 with Aeroplan or BA Avios.

Some people prefer this card over the Aeroplan Plus Gold, since it accrues MR points, which are more flexible to use (convert when needed, frustration with Aeroplan, etc).

Plus, since the Gold Rewards card earns 2x points on gas, groceries, pharmacy (Shoppers, Rexall, etc) and travel (flights, rental cars, hotels, etc.) then it's actually preferred as a main go-to card. Most people just sign up for the Aeroplan Plus Gold to get the 30,000 welcome points, and to refer other people, but don't actually spend (much) with it, unless they don't have a better card to use.

The CIBC and TD cards also give Aeroplan signup points, but for 20,000 / 15,000. However, neither of these cards are currently offering waived FYFs. Wait another month or so...should be coming back on promo soon, if history repeats itself; for CIBC, anyway...the TD card was newly introduced, as of Jan 2014.
