Rookie Ryan Borucki pitched eight innings of three-hit ball for the Blue Jays, who have won 13 of 17 games between the two bottom teams in the AL East.
Toronto stands 25 games better than the Orioles, whose 43-107 record is worst in the majors.
The only other Orioles team with 107 defeats was the 1988 club, which started 0-21 on its way to a 54-107 finish.
This Baltimore team has been blanked 15 times and owns a major league-worst 26-49 record at home.
Only 8,198 fans showed up at soggy Camden Yards to watch yet another defeat.
The franchise record for losses is 111, by the 1939 St. Louis Browns. After going 54-100 in 1953, the Browns moved to Baltimore.
The major league record is 120 losses, set by the expansion New York Mets in 1962.
