Of course! Make sure you add the $3 call forwarding option in Koodo self-serve, and make sure your plan includes unlimited nation-wide calling (if you need that). You can forward an AB number to a QC number.
If you plan on using the AB number for call forwarding only to the QC number, it'll likely be more cost-effective for you to port the AB number to a VOIP carrier (such as Fongo/Freephoneline, or even Voip.ms). Fongo/Freephoneline will work at no monthly charge assuming that the QC number is from a major QC city (like MTL/QC city/Gatineau/etc.).
If you don't add the $3 call forwarding option in self-serve and you call forward on pay per use, you'll likely rack up a hefty bill. Also, if you're not on unlimited nation-wide calling as part of your plan, you can incur hefty usage charges.
If you must do cellular call forwarding long term, consider pre-paid options like Public Mobile or Chatr who likely include call forwarding at no extra charge.
