I would think of two or three different items.
Firstly, as I explained, I think Canada should, perhaps through quiet diplomacy or otherwise, demand the release of certain prisoners. The Iranian regime has been taking prisoners for a long time and using them as hostages in effect. As I explained, the arrest of dual nationals, or simply people with foreign ties, is by deliberate design. I think that Canada should demand the release of Saeed Malekpour and the release of the seven Baha'i leaders. That is one concrete step that Canada can make.
Secondly, Canada can make it clear that resumption of trade and diplomatic relations will come hand in hand with a regular dialogue on human rights, and not the dialogue that happened with the Europeans during the Khatami regime, when nothing in fact changed on the ground.
Thirdly, I think Canada can continue to support the mandate of Dr. Shaheed, and continue to sponsor resolutions, which it has since 1980.
I think at three levels, Canada could engage in a kind of principled pragmatism in its relations with Iran.
