This is 44-73347 which served with the RCAF as #9298, seen here in the colours of No. 443 Sqdn and coded PF-298; it went to the Canadian War Museum in August 1961 where it still is today, but in camouflage.
From the blurred number on the tail it looks like this mustang is 9298. the list I have lists it as 44-73347 and is or was in the the Canadian National Museum Rockcliffe .
Could that pic be taken at the OLD Vancouver airport? I have pics of 6 planes like this - here - http://caterwauls.ca/reflections.htm but mine have a "Bee" insignia on them. The area looks familiar to me.
