That would be Callum Keith Rennie (more blondish) He is Ray K, the slasher's dream (as Paul Gross--the Mountie--actually mentioned in an interview) He came after Ray V. I adore Due South because

a) there's a gen season and a slash season and you can swing both Rays (as I do)

b) Fraser (the Mountie) changes as you watch him with each Ray, the partnerships of both being slightly different because Fraser was different

c) it has one of the best finales in television history--the partners rode off into the sunset together to have a Candian adventure, just the two of them

It's definitely a show you should try, definitely. SO much love.
