Had several new ones last year which I brought in for the winter (until I
have bulked them up and can risk them out) Thing is they have not died
back
as I expected, should I cut them down anyway or leave the new unflowered
shoots and only remove the old?



My experience:

Leave the cannas they will grow away well once it warms up

Cut back the gingers - mine died back and put up new shoots after i planted
them out when I was in your situation
