By Dr. Miriam Osei, Organic Agriculture Certification Specialist · Rating: 4.6/5 ⭐⭐⭐⭐⭐ · Keyword: PACS Certified Organic Seeds vs Conventional Seeds
“The most common misconception I encounter in home gardener education is conflating ‘untreated' with ‘organic.' They are related concepts, but they describe different things and carry different implications. An untreated seed has not been coated with fungicides, insecticides, or other synthetic compounds after harvest. That's a meaningful distinction from treated conventional seeds — neonicotinoid seed treatments in particular have well-documented effects on soil biology and pollinators that persist well beyond the planting season. But ‘untreated' says nothing about how the seed was produced. It could have been grown in a field with heavy synthetic fertilizer and pesticide application throughout the season. Certified organic seed, by contrast, describes the full production environment — the soil it was grown in, the inputs used or not used throughout the growing season, and the handling practices after harvest. PACS certification in particular is a rigorous accredited standard — it's not a self-administered checklist. For gardeners who want their growing system to be organic from first principles, starting with certified organic seed is the most consistent approach. For home gardeners who can't always access certified organic seed in the variety they want, untreated non-GMO seed is a reasonable alternative — it maintains the no-chemical-treatment principle even if it doesn't carry the full organic production chain certification.”

The Seed Certification Confusion — and Why It Matters
Walk through any garden centre and you'll see seeds marketed as “organic,” “natural,” “chemical-free,” “eco-friendly,” “untreated,” and “non-GMO” — often on products from the same shelf, from companies with very different actual commitments behind those labels. For most gardeners, these terms blur together into a general sense that the seed is somehow better for the garden and the environment. The specific differences between them are rarely explained — and for buyers making decisions based on organic principles, those differences are not minor.
PACS certified organic seed — the certification held by West Coast Seeds under registration #16-205 — represents a specific, independently verified standard that goes considerably further than “untreated” or “natural.” Understanding what PACS certification actually covers, and how it differs from conventional seed production, is what makes the difference between buying with confidence and buying with hope. Here are the four key differences.
What Is PACS Certification? The Certifier Behind West Coast Seeds
PACS — the Pacific Agricultural Certification Society — is an accredited, independent third-party organic certification body operating in British Columbia, recognized under Canada's Organic Products Regulations. PACS certification is not a badge a company creates for itself or purchases from a marketing organization. It requires application, documentation, inspection, and ongoing compliance with accredited organic standards — administered by an organization with no financial relationship to the company being certified.
What PACS Certification Covers for West Coast Seeds (Registration #16-205):
- Seed grower verification: The farms and growers who produced the certified organic seed varieties have been verified to use organic production methods — no synthetic pesticides, no synthetic fertilizers, no prohibited inputs throughout the growing season
- Full production chain: Certification covers the entire path from organic seed grower to West Coast Seeds' handling and storage — not just the final product on a shelf
- Handler certification: West Coast Seeds holds Certified Handler of Organic Seed status — meaning the processing, sorting, packaging, and storage of organic seeds meets certified organic handling standards, preventing contamination with conventional seeds or substances
- Ongoing compliance: Organic certification requires annual renewal, inspection, and documentation — it's a maintained standard, not a one-time badge
- Supplier certificate documentation: West Coast Seeds holds organic certificates from their seed suppliers — the certification extends upstream to the growing operation, not just to West Coast Seeds' own facilities
4 Key Differences You Need to Know Before Buying
① Production Environment: Organic Soil System vs Synthetic Input System
The most fundamental difference between PACS certified organic seeds and conventional seeds is not what happened to the seed after harvest — it's where and how the seed was grown. Certified organic seeds come from organically managed growing environments: no synthetic pesticides, no synthetic fertilizers, no genetically engineered inputs, no prohibited substances throughout the entire season from soil preparation to harvest. The plant that produced the seed was itself grown in a certified organic system.
Conventional seeds come from conventionally managed growing environments that may use synthetic pesticides, synthetic nitrogen fertilizers, herbicides, and other inputs throughout the season. Even when the seed itself is not treated after harvest (untreated conventional seed), it was produced in a growing system that organic principles specifically avoid. For gardeners who want their organic garden to be consistent from the seed forward — not just from the soil amendment forward — the production environment difference is the substantive one. A PACS certified organic seed arrives with a verified production history that starts in organic soil.
② Seed Treatment: No Chemical Coatings vs Common Synthetic Treatments
This is the difference most home gardeners are already aware of — seed treatment coatings — but the full scope of conventional seed treatment is worth understanding. Certified organic seeds (and all West Coast Seeds varieties) are untreated — no fungicide, insecticide, or other synthetic coating applied after harvest. What you plant is the seed in its natural state.
Commercially treated conventional seeds are coated with synthetic compounds — most commonly fungicides (thiram, captan) and insecticides including neonicotinoids (imidacloprid, clothianidin, thiamethoxam). Neonicotinoid seed treatments are systemic — the compound is absorbed by the growing plant and present in pollen, nectar, and plant tissue throughout the season. Research consistently documents effects on bee populations, soil invertebrates, and beneficial insects from neonicotinoid-treated seed in agricultural settings. These coatings are often colour-coded (bright pink, blue, green) to warn handlers — treated seeds should not be handled without gloves or inhaled. For home gardeners buying from general garden centres without specifically seeking untreated seed, treated conventional seeds are common. PACS certified organic seeds carry neither the production inputs nor the post-harvest treatments.
③ Independent Verification: Third-Party Certified vs Self-Declared
In the seed market, the gap between what companies claim and what they've verified is significant. “Natural,” “chemical-free,” “eco-friendly,” and even “organic” are commonly used as marketing descriptors without independent certification — because Canadian regulations prohibit using the word “organic” to describe certified organic seeds only when it's a formal certified organic claim. Many smaller seed companies use organic-adjacent language without the certification to back it up. PACS certification is independent third-party verification — PACS has no financial relationship with West Coast Seeds, no incentive to certify what shouldn't be certified, and is accredited under Canada's Organic Products Regulations.
Conventional seed companies have no equivalent verification requirement for claims like “natural” or “eco-friendly.” These terms carry no regulated definition in the seed market. West Coast Seeds' published PACS registration number (#16-205) is the specific detail that separates a certified claim from a marketing claim — it's a number that can be looked up, cross-referenced, and verified by any buyer who wants to confirm it. That level of transparency is not standard in the seed industry.
④ System Alignment: Full Organic Chain vs Partial Organic Practice
For home gardeners building organically managed gardens, there is an internal consistency argument for certified organic seed sourcing that goes beyond any individual input concern. An organic garden built on certified organic seeds is consistent from first principles: the seed came from an organically managed plant, was handled by a certified organic handler, was planted in organically managed soil, fed with organic amendments, protected with organic pest management. The chain is unbroken. An organic garden planted with conventional seeds — even untreated, non-GMO conventional seeds — introduced a break in that chain at the foundation. For many home gardeners this is an acceptable pragmatic compromise, particularly when certified organic seed isn't available in a desired variety.
For certified organic farms operating under formal accreditation, this isn't a philosophical preference — it's a regulatory requirement. Organic standards require that certified organic seed be used when commercially available, and treated seed is never permitted. The system alignment argument is strongest at the farm scale where certification depends on documented input sourcing. For home gardeners, the choice between certified organic and untreated conventional seed is more nuanced — but for those who want to be as consistent as possible with organic principles from the ground up, starting with PACS certified organic seed is the most coherent approach available.

Who Needs Certified Organic Seeds — and When Untreated Is Enough
✅ Choose PACS certified organic seeds if:
- You operate a certified organic farm and require documented seed sourcing for your certification audit
- You want your organic growing system to be consistent from the seed's production origin forward, not just from your soil management forward
- You want the most verifiable, independently confirmed organic standard available — PACS #16-205 can be looked up and confirmed by any buyer
- You're building a garden that aligns with organic principles at every input level, including the seed itself
- You're concerned about the production environment's impact on seed genetics and adaptation to organic soil management
⚠️ Untreated non-GMO (all West Coast Seeds) is sufficient if:
- You want the no-chemical-treatment assurance without requiring full organic production chain certification
- The specific variety you want is not available in a certified organic version — untreated non-GMO is the practical alternative when certified organic isn't commercially available
- You're a home organic gardener who manages your growing environment organically but doesn't require documentation of seed sourcing provenance
- The variety is a hybrid for which certified organic seed may be less commonly available — WCS carries some hybrid varieties that are untreated and non-GMO without full organic certification
⭐ Final Verdict: PACS Certified Organic Seeds vs Conventional Seeds
The four differences between PACS certified organic seeds and conventional seeds are not marketing distinctions — they're production, treatment, verification, and system alignment differences with practical implications for how your garden starts, what enters your soil, and how consistently your organic growing principles hold from the seed forward. The neonicotinoid seed treatment issue alone is a compelling practical reason to seek untreated seed sources; the full organic production chain that PACS certification verifies goes substantially further.
West Coast Seeds' position in this comparison is the clearest in Canada: every variety in the catalogue is untreated and non-GMO, certified organic varieties carry PACS registration #16-205 that any buyer can verify, and the company holds Certified Handler of Organic Seed status that extends the certification to handling and storage. For the home organic gardener, the starting point is the most reliable in the Canadian market.
Conventional seeds are not the enemy of good gardening — for many purposes, untreated non-GMO seed is entirely sufficient. But for gardeners who want to know exactly where the organic chain begins and ends, PACS certification is the most specific, verifiable answer available in Canada.

Frequently Asked Questions
What is PACS certification for seeds?
Pacific Agricultural Certification Society — an accredited independent third-party organic certifier in BC, recognized under Canada's Organic Products Regulations. West Coast Seeds holds registration #16-205. Covers the seed's full production chain: organically managed growing environment + certified handler status for processing and storage.
What's the difference between certified organic and untreated seeds?
Untreated: no chemical coating after harvest (all WCS seeds). Certified organic: full production chain — grown in organically managed soil, no synthetic inputs throughout the season, certified organic handling and storage. Organic covers the seed's origin; untreated covers what wasn't done to it after harvest. Both apply to WCS certified organic varieties.
Do certified organic seeds grow better?
Not necessarily — the certification describes production, not performance. Germination potential depends on variety, storage, and growing conditions. WCS addresses germination separately through Canada No. 1 germination standard testing for all varieties, organic and non-organic alike.
Are conventional seeds harmful?
Treated conventional seeds — particularly those with neonicotinoid insecticide coatings — have documented effects on soil biology, earthworms, and pollinators that persist through the growing season. Untreated conventional seeds don't carry coating risk but were still grown with synthetic inputs. For organic gardeners, both concerns are reasons to seek untreated non-GMO or certified organic seed sources.
Does West Coast Seeds carry PACS certified organic seeds?
Yes — PACS registration #16-205. Certified organic varieties clearly marked in the catalogue. Also a Certified Handler of Organic Seed and holds organic certificates from seed suppliers. Registration number is publicly listed on the WCS About page and independently verifiable.
Can I use conventional seeds in an organic garden?
Certified organic farms: treated seeds are prohibited; untreated by exception only when certified organic not commercially available. Home organic gardens: untreated non-GMO is a reasonable alternative when certified organic isn't available in a desired variety. For fullest organic alignment, PACS certified organic seed is the consistent choice. Browse certified organic varieties: westcoastseeds.com →
