Do I have to wait for yellow leaves before digging up Canna ?

Its my 1st year with cannas in zone 5, Ontario. One set is in huge pot, the other in the ground. All bloomed well, although I received the ones in the ground late and they only started to bloom at the end of summer. Hubby is anxious to get the garden cleaned up and wants me to remove the tubers now. Is is safe to do this now while the blooms are fading but leaves are still green and healthy, or do I have to wait till frost has triggered the leaves to die back? I suspect I should wait, like with tulips, one needs to allow the leaves to die down naturally so they can provide nourishment to the bulbs for the following year' s flowers.....
