Narrative:

Ramp notified flight deck that 'aircraft was ramp ready for push all doors closed.' we called for push clearance and completed checklist and preparations for push. Contacted ramp and advised brakes released and cleared to push with push instructions. Ramp confirmed but didn't push. I asked ramp why we weren't pushing he advised there was a loading problem and he would be back. I cancelled our push clearance and made a PA to passengers. After ten minutes and hadn't heard from ramp I contacted the load planner on my cell phone. He advised that the ramp had improperly loaded cans which would prevent approximately 6 cans from being secured on the floor grid; which would allow them to shift aft on rotation. This obviously would put the aircraft out of C.G. And possibly make the aircraft uncontrollable. Finally another ramp agent advised that the original ramp crew was gone and that they are going to download and reload the cans properly. This process took approximately 30 minutes to accomplish. This issue with this is that it was not the first or only time this exact incident had taken place as the captain experienced the same issue only a few days before. That fact only takes this situation to a conclusion that we have a serious ramp training issue or this incident had another motive. Regardless; this is extremely concerning and the safety and operational trust issue is not acceptable.
