Schnur, a 23-year-old from Montreal ranked 154th in the world, defeated 10-time ATP title winner Querrey in one hour and 54 minutes.
He will try to complete a fairy-tale championship run against American Reilly Opelka, who outgunned top seed John Isner 6-7 (8/10), 7-6 (16/14), 7-6 (7/4) in the other semi-final. The all-American showdown set a Tour record for the most combined aces in a three set match with 81. The previous record was 71 set by Australian Nick Kyrgios and Ryan Harrison earlier this year in Brisbane.
Schnur, the last alternate in the qualifying draw, had been winless in five career tour-level matches. "It's an extremely big moment for me," said Schnur.
Querrey, 31, was in his first ATP semi-final since last year in New York, when he lost to Kevin Anderson in the final.
