I received canna lily rhizomes from a friend. Followed instructions for planting and watering, and now waiting for some sign of life. How long should it take?

Are they planted in the ground? It may be quite cold yet for the rhizomes to grow. They will sprout only when the soil temperatures are warm enough.
You can start them in pots to give them a head start.
If you do not see signs of growth you may want to gently dig and check on the bulbs. Try not to disturb the top if they have sprouted.
If they do not grow it may be they have rotted in the ground.
