Highest THC Flower Available in Ontario, Canada

In order to qualify for this list a product needs to have consumer cannabinoid reports available from at least 4 different batches. Though there are some products with a higher average potency, the intention here is to highlight producers that have proven themselves over time. A product also needs to be currently available online in the Ontario Cannabis Store. This isn't an archive of the potent product you could have bought 6 months ago.

In the Avg THC column, the dark bar inside the white bar indicates the average reported thc content(dark bar) in comparison to the highest recorded potency for a single batch across all products(White Bar). The thin gray bar indicates the range between the minimum and maximum consumer reported THC content.
