if i am reading this (https://www.canada.ca/en/health-can...-industry/frequently-asked-questions.html#a34) correctly, it looks like you need a license. "Note that producing (e.g., cultivating, harvesting) industrial hemp in accordance with the IHR always requires a licence." the webpage was updated nov 7th of 2018 so it is pretty current. could you just grow some and claim you thought it was regular cannabis or are you looking at growing a big crop? might not hurt to contact the office of controlled substances for clarification and request written documentation from whomever you speak with.
