> **The framework in one line:** a Canadian vendor worth using ships **domestically** (no border risk), backs its products with **independent testing you can verify yourself**, and answers testing questions **openly**. Everything else is secondary. Research/educational use only.

## 1. Domestic shipping

This is the Canada-specific filter. A vendor shipping from inside Canada avoids customs delays and seizures — the most common practical problem with overseas orders. Confirm a real Canadian address and domestic fulfilment before anything else.

## 2. Verifiable independent testing

No regulator checks these products, so testing is your only quality signal. But "testing" only counts if it's independent and verifiable. Ask: does the Certificate of Analysis resolve on the *lab's own* portal (not just a vendor PDF)? Is the lab used by many competing vendors, or only this one?

## 3. Transparency under questioning

Email and ask how they test. Specific, open answers and a portal link are good signs. Vague "trust us" replies or "ISO-aligned" weasel wording are not.

## 4. A findable, consistent reputation

Look for a consistent presence across independent communities over time — not a brand that appeared last month with only its own glowing words.
