With regard to personal cultivation for adult use, the cannabis act recommends a four-plant limit for individuals over the age of 18 in a single household. While that is a step forward from zero plants, some of the limitations are pretty arbitrary with regard to how the plant grows and how adults can manage this type of growth. Currently under the cannabis act, plants can be no taller than one metre, which is very restrictive with regard to certain strains of plants that may, just by nature, grow more robust than that limit.
