Actually Canada has sent aid several times to the US in earth quakes , 9/11 and tornadoes. One year we sent a bunch of engineers to help with a earth quake. and to pay us back they later sent up the PRIME RIB (military engineer group out of the south (i think)) to help renovate a couple of base's barracks (too bad we had to rip it out becaause it didn't meeet Canadian Building codes ( the thought was there).
And we sent our DART team already (diseaster response team). So dont look north with contemp we have allways helped when diseaster strikes.
Still best wishes to all affected
