Canada reacts to Iran

So, I read a Canadian news report on today's closing of the Iranian embassy and it boils down to this:

"The calls were sparked by a July news report that said Iran's cultural counsellor in Ottawa, Hamid Mohammadi, suggested Iranian expatriates should be nurtured to be of service to Iran."

I doubt this is a policy isolated to Canada, rather this is Iran's global policy.
