Currently, many spices that are imported into Canada are not safe for human consumption either because of a high microbial load or because they may contain sticks and stones and other natural substances that have to be removed.
What Canadian processors do in Canada is they treat them so they're microbially safe and they process them to remove the sticks and stones. Then they're packaged for either sale directly to consumers or for further processing with other Canadian manufactured and exported goods.
If these products are prohibited from being imported into Canada, which is what the act currently says, access to those raw spices, which currently support those jobs in Canada, will be lost.
