Unfortunately, there are so many pieces of legislation within which there are export restrictions and regulations relating to exports.
The first act to look at is the Export and Import Permits Act, and the export control list and the area control list under it.
The second obvious one is the United Nations Act and the Special Economic Measures Act, which in some cases relate to goods, but in many cases relate to listed persons and prohibitions on doing business with particular listed persons. You need a lot more information about a particular good to know whether that good should be restricted in some way or another. Then we have, for rough diamonds, for honey, for maple products, and so on.... There are over a hundred, if not over a thousand, different pieces of legislation that have restrictions on exports in one way or another.
That's why they say “another act of Parliament” as a catch-all basket, but it doesn't really help small to medium-sized businesses or individuals.
