Cannabis Dispensary Near Ontario, Canada

If you’re crossing into Buffalo from Ontario, you already know that a trip to Western New York is rarely just one thing. It’s groceries, it’s shopping, it’s a Bills game, it’s dinner somewhere you’ve been meaning to try. Mammoth Cannabis on Ohio Street is one more reason to make the most of the visit. We’re proud to be a part of what the local Buffalo market has to offer.

Legal Cannabis, New York Style

Ontario has its own cannabis market, but New York’s legal dispensary scene offers something different — locally grown products, regional cultivators, and a selection that reflects the character of Western New York rather than a national retail chain. At Mammoth, we carry a rotating inventory of cannabis products from local and regional growers, and the difference in variety and quality is something Canadian customers notice.

One thing worth knowing before you visit: cannabis purchased at Mammoth is for consumption within New York State. It cannot be transported across the border back into Canada. Plan to enjoy it during your visit, and plan accordingly.

Discounts for Our Canadian Visitors

We appreciate the trip, and we show it. Mammoth offers special pricing for customers visiting from Ontario and across Canada. Ask a staff member when you come in and we’ll make sure you’re taken care of. It’s our way of saying thanks for choosing to include us in your New York stop.

What We Carry

Our inventory covers the full range — flower, pre-rolls, vapes, edibles, concentrates, and tinctures — with a focus on local and regional products that you might not find on the other side of the border. The selection rotates based on what’s fresh and worth carrying, so there’s usually something new to explore.

For Ontario customers curious about vapes, Florist Farms‘ AIO vapes are worth a look. All-in-one devices are as straightforward as it gets — no cartridges to swap, no battery to charge separately, ready to use right out of the package. Florist Farms is a New York State cultivator, so what you’re getting is locally grown and processed. Our staff can walk you through the options and help you find the right fit.

From the Peace Bridge to Ohio Street

If you’re crossing at the Peace Bridge, Ohio Street is practically the first place in Buffalo that opens up in front of you. It’s a natural first stop before you head deeper into the city, or an easy last stop before you make your way back to the border.

Buffalo and Ontario share more than a border — there’s a genuine back-and-forth between these communities that goes back generations. Sports, shopping, family visits. Mammoth fits into that relationship naturally.

A Dispensary Worth Crossing For

Mammoth is family-owned and operated, which means the experience is personal from the moment you walk in. No corporate script, no pressure, just knowledgeable staff who want to make sure you leave with something you’re genuinely happy with. For first-time visitors and regulars alike, that’s the kind of thing that brings people back.
