About Us.


1 hershey Drive

1 Hershey Drive in Smiths Falls, Ontario consists of eight buildings representing over 470,000 square feet of manufacturing and distributing space situated on approximately 39.6 acres of land.

Tweed's operations occupy 180,000 square feet of this space, 168,000 of which is licensed for marijuana production.

The site was originally selected by the Hershey Company in the early 1960s to be its first plant outside of Hershey, Pennsylvania. It is said that Smiths Falls was chosen because of the plentiful supply of milk and water, as well as its ideal position between Toronto and Montreal and access to important transportation infrastructure, an advantage Tweed continues to enjoy today.

Tweed farms niagara on the lake

Tweed Farms, our sister company, is located in the heart of Southwestern Ontario’s wine country in Niagara-on-the-Lake.

By using the sun’s energy and closed loop water systems, the greenhouse at Tweed Farms is an environmentally friendly operation capable of growing large quantities of natural medical marijuana.

The site currently houses 350,000 square feet of greenhouse, and as far as we know, it is the largest marijuana greenhouse in the world. Plans are already being developed for a second building at the 20-acre location to allow on-site harvesting and processing.

Originally built in the early 1990s, the site has been used to grow an array of produce for national grocery chains- tomatoes, herbs, cucumbers and most recently eggplants- there’s a chance you’ve already consumed something grown at Tweed Farms!
