Your consulate for immigration purposes will be either Vancouver, or Montreal, the one in Calgary only does visitor types of visas.
The link to London DS-2001 will give you a good idea what will be needed and asked for on DS-169, Police cert, Birth cert, Divorce cert, Death cert, ect...
Don't get a police cert until you are closer to interview, they have a 1 year life.
Some useful info can be found here:
