Gardening Retailers

At OSC Seeds, our goal is to provide Canadian gardeners with the best quality seed available at competitive pricing. Through our main OSC Seeds brand and the Aimers Organic seed brand, we offer a wide variety of seed products for sale across Canada.

Our fifth-generation family business has over 125 years of growing history and is proud to be wholly Canadian-owned and operated. From our central facility in Kitchener, Ontario, we ship from coast to coast across Canada.

We match our high quality product offering with knowledgeable and experienced staff, helpful customer service, and on-time deliveries across the country. Learn more about our retailer product offerings below.

Colour bars on the top of the packets indicate herbs, annual flowers, and perennial flowers. OSC vegetable packets have no colour band.

Packets are UV coated on the front picture to enhance the appeal of the picture. This is unique in the Canadian market.

Heirloom vegetables are identified with a green banner through the picture. All vegetables are labeled with the days to harvest on the back flap.

Concise sowing directions are printed on the back panel in English and French. UPC codes for OSC seed packets are printed according to the packet price point. Competitive retail prices are printed on the front corner of the seed envelopes.

OSC Seeds is a proud distributor of Aimers Organic seeds.

The Aimers Organic brand offers a wide selection of organic vegetable and herb seeds in attractive, easy-to-read, full colour packets. Bilingual sowing instructions are printed on the reverse of each packet and a special info tab describes the organic certification guarantee that comes with all Aimers Organic varieties.

All packets carry a unique bar code allowing retailers to track individual packet sales. All Aimers Organic seeds are 100% open-pollinated, contain no hybrids or GMOs, and are certified organically grown seed by The Centre for Systems Integration (CSI), a fully accredited certifier under the Canadian Organic Regime (COR).

Displayers are constructed of corrugated modular panels with clear plastic pockets or with sturdy metal wire, which show almost all of the packet picture. For greenhouse areas, we recommend a metal display, which will tolerate moist floor conditions.

All replenishment orders of garden seed packets are shipped with postage prepaid by OSC Seeds. Please email your replenishment packet orders to or by fax to 519-886-0605.

All OSC and Aimers Seed products are of the highest quality available, surpassing Canadian Food Inspection Agency (CFIA) and The Centre for Systems Integration (CSI) standards for germination and purity. Seed is only contracted to reputable sources from countries around the globe.

Aimers Seed Tapes are available on clip strips with the regular OSC displayers. Seed tapes take the guesswork out of thinning seedlings in the garden. Seed tapes are available in Beet, Carrot, Lettuce, Mesclun Mix, Spinach and Radish on a consignment basis.

OSC and Aimers Seed is sold on a consignment basis. Please contact one of our representatives to discover the benefits and advantages of consignment seed packets. We also offer bulk seed in sizes of up to 25 kg. as an outright sale. Please note that special shipping charges apply for outright sales (FOB: OSC Plant in Kitchener).

Displays are configured with seed types suitable to the areas of Canada where they are shipped. All regular displays contain herb, vegetable, annual flower, perennial flower, and wildflower seeds. Subsequent packet orders are shipped postage paid. OSC reserves the right to limit display size and type.
