Keep in mind that no provider can guarantee indoor cell reception due to variables in building materials, construction in/around your building that may affect signal, etc. Your best bet is to try it out. You can cancel postpaid service within 15 days.
I've been there a couple time when going to Calypso, always have perfect reception. Now that will vary if your in a very bushed in area, but if you have reception with rogers/bell/telus u'll do fine with Koodo!
