After some technical and legal work, I now have a number of imagery layers hosted on a rented server.
These layers cover from Vancouver to Hope in 20cm or better and Lions Bay to Pemberton as 40cm or better. 10cm imagery is available for Vancouver, Richmond, Ladner, West Delta, the North Shore, Whistler and Surrey.
Most of the imagery was taken in 2009, but Surrey is from 2011.
I've prepared a page with links to the imagery and Potlatch2 and JOSM URLs at http://imagery.paulnorman.ca/tiles/about.html
Some layers may be slow initially loading at high zooms as they may need to fetch from a remote server.
An example of two layers from there and Bing is http://imagery.paulnorman.ca/tiles/surreyexample.png. Starting in the top left going clockwise the layers are Surrey2011, DataBC bc_gvrd_east_2009 and Bing.
