“Can I make my own edibles for consumption at home”
There is nothing in the Cannabis Act that would prohibit you from making your own.
However, be aware of the possession limits prescribed in the Act (as of October 2018) - it states that 15g of edible product would be equivalent to 1g of dried flower. Thus, the max possession per adult of edible product would be 450g (15 x 30g), assuming that is the entirety of the cannabis you possess. If you possess other types, you would need to take those into account of the max allowed, which is 30g Dried Flower Equivalent.
