Every other month.

I'm still carrying multiple cards in my wallet from that year-long opening spree (FYF, 25K, no minimum spend, Aeroplan Distinction-eligible welcome points).

Caution if you're going to open as a sole proprietorship without a legitimate business registration number. Nowadays it's not as lax as it used to be. Hope you get a good rep.

Someone in this thread opened the Aerogold Business Visa as FYF with a phone rep, just a few months ago. Maybe he can chime in on his experience with this.
