How long does it take canna bulbs to start poking through the soil.?

This depends on when and how deeply you plant. Generally, in spring or summer, cannas will appear within two weeks. They love water, so water heavily the first year. For those who plant in fall, look for cannas after the daffodils have bloomed. As days grow warmer, the shoots will seek sunlight. Plant corms anywhere from 2-4 inches below soil depending on soil type. Heavier soils such as clay are hard to push through, so plant in clay more shallowly.
