Five Tiers of Quality Cannabis — Transparent Pricing
Our unique tier system ensures transparent pricing and quality grading so you always know what you're getting. Exotic ($10-$12/g) features top-shelf, ultra-rare genetics with THC levels reaching 35-39% — these are the strains connoisseurs travel across Ottawa to find. Premium ($7-$10/g) offers connoisseur-grade strains at THC 32-34%, balancing quality and value. AAA+ ($5-$6/g) delivers heavy hitters at THC 30-32% — our most popular tier for experienced users. AA ($4/g) provides quality daily drivers at THC 27-29%, perfect for regular consumption. Budget ($3/g) offers value ounces from $40 without sacrificing reliability. Every tier is lab-tested, properly cured, and freshly rotated.
Beyond Flower — Edibles, Vapes, Concentrates & More
Castle Heights Cannabis is more than just a flower shop. We carry a comprehensive selection of cannabis edibles (gummies, chocolates, baked goods), vape pens and disposable vapes, concentrates (shatter, wax, hash, diamonds, live resin), pre-rolled joints, magic mushrooms, native cigarettes, rolling papers, and accessories.
