Hello farney bhoy,
I've contacted my Canadian consultant who has confirmed that , unfortunately, all PAFSO members are on strike now worldwide including CHC, London. However, he said it wont take much longer , he said, and the government should sort things out soon, he's also expecting 30 to 45 days delay in normal processing.
In addition to the above I've read the updated article about this topic in Radio Canada int'l site which , in some way, matches what my consultant has concluded. http://www.rcinet.ca/en/2013/06/07/strike-by-canadian-diplomats-spreads-worldwide/
Best wishes,
