This is the ultimate in bragging rights.
Here's the farewell email he's said to have sent to staff last week:
It is with sadness that I am emailing you to say farewell on my final day here at BMO. However, it is with great pride and excitement that I am able to announce my future plans.
Just this week, I was informed that I was selected from among tens of thousands of applicants to participate in a highly experimental civilian space travel program coordinated by NASA and the U.S. government. In September I will pack my bags for Florida where I will begin a one-year training program, which will culminate in a six-month trip to the International Space Station. Unfortunately, I cannot divulge too many details about the program and our mission but suffice to say, this will be a once-in-a-lifetime experience. If for some reason I should not return, please know that it was pleasure working with you all.
