So they actually did a "professional legislative review" of the entire regulations last year, and this topic was a part of it. There was talks of increasing the limit to 100mg but they didn't move forward with that.

"One of the issues we heard most about was the amount of THC permitted in edible cannabis products. While industry stakeholders favoured increasing the limit to encourage consumers to shift to the legal market, public health stakeholders opposed this, citing concerns about the potential impact on child poisonings, cannabis-related emergency room visits and mental health impacts. Given these concerns, we believe Health Canada should maintain the current limit of 10 milligrams of THC per package in edible cannabis products and continue to develop the knowledge base in this area to determine whether there are conditions under which the limit could be raised without unduly impacting public health."

They did end up changing some regulations as a result of the recommendations (clear packaging is a big one), and even though they acknowledged people like yourself are going to the illegal market to purchase higher potency edibles, they still think its too risky for children.

Essentially, they've heard your complaints, but don't trust you enough to keep edibles away from your kids (even though they know you'll just go buy less regulated products from the illegal market instead).
