The Conservative stimulus program was well managed.  As Paul Welles writes in “The Longer I’m Prime Minister”: “the auditor general would even congratulate him on the care he and his officials had taken in ensuring that the proper rules were followed in disbursing the money”. 
I don’t know what surplus you are talking about. There was a $1.9B surplus in 2015-16, and the PBO said there would have been a $2.9B surplus in 2016-17 if Justin “the budget will balance itself” Trudeau hadn’t turned it into a $1B deficit. The $2.1B revenue from the General Motors sale, presumably the one-off sale you are talking about, was in 2015-16, not 2014-15. Even if you deduct the $2.1B from the PBO’s estimate of a $2.9 surplus for 2015-16 you still get a surplus. 
Why do you consider deferring spending a "bogus" way to balance a budget? Isn't deferring optional spending something everyone does to help balance their budgets?
