I think he is getting excellent advice from his doctors. Princess Margaret Hospital in Toronto is one of the leading prostate cancer hospitals in the world, imho. Sunnybrook Hospital in Toronto is excellent for radiation oncology. If you have the wherewithal to travel for second opinions, it's certainly worth hearing, but I don't think anyplace in the US has better doctors.
Because his pathological stage was not T3 or T4 and there were no positive margins, it raises suspicion that the cancer is not local, and may be micrometastatic and systemic. Your doctor is also correct that the length of hormone therapy following radiation has not been definitively established. Most would start him with 2 months of hormone therapy
before the salvage radiation, continue it through the 7 weeks of radiation, and then keep going for a while afterwards. That clinical trial will help us learn the optimal duration. I think for a GS 9, most would continue it for 1 1/2 to 2 years after.
If you are not ready to make a decision yet, a 4 month Lupron shot will slow or stop progression for now, and will be necessary anyway in case you decide to get salvage radiation. There are several clinical trials of adjuvant immunotherapies, advanced hormonal therapies, and growth factor inhibitors that he may qualify for as well.
His PSA is too low for much of anything to show up on advanced imaging (e.g. PET/CT). One interesting new possibility is a new kind of scan called a PET/MRI that may be able to detect much smaller tumors and at lower PSAs than PET/CT scans. Fortunately for you, the Lawson Health Research Institute in London, Ontario is doing a clinical trial now.

Another option is to do nothing, and wait until symptoms emerge, which is likely to be many years from now, and treat them then with hormone therapy and/or chemo.
One has to learn to live with uncertainty. The state of the science isn't where any of us would like it to be.
