I get small orders of seeds from US suppliers all the time.
Flower seeds do not seem to have restrictions?
Veges seem restricted according to seed sizes:
Only up to 500 grams (about 1 pound) for small seeds ( smaller than radish seeds)?
There is a 5 Kg restriction on larger seeds such as peas, beans etc.?
But some USA suppliers do not ship to Canada---too expensive to comply with Canadian rules?
