Looking at the FBI data for 2014, Portland would indeed be #1 by a large margin among cities with more than 500,000 inhabitants if the current annualized 1.1 rate holds through the whole year. San Diego is at 2.3 but of course includes massive areas that would be low crime suburbs of most typical cities.

Toronto had a murder rate of 2.0 in 2012 and Vancouver 1.2. Canada as a whole has a rate of 1.6

I don't have city level data but the national averages for the following countries is: Australia 1.3, England and Wales 1.0, Ireland 1.0, New Zealand 0.9, Sweden .9

Among major cities I found 2009 data with the following homicide rates: Amsterdam 4.4, Glasgow 3.3, Brussels 3, Prague 2.7, Seoul 2.4, Warsaw 1.9, Berlin 1.8, London 1.6, Helsinki 1.2, Oslo 1.2, Vienna 1.1, Madrid 1, Tokyo 0.4, Lisbon 0.2

It will be interesting to see if this is a permanent development or a statistical blip and we will see Portland revert to the mean. In any case the current numbers are fantastic and world class, in a good way.
