Jamie Longworth's last-minute goal was enough for Queen's Park to see off 10-man Montrose and leapfrog Stranraer into second place in Division Three.
Both sides were frustrated by fine goalkeeping performances in the first-half.
Gary Wood was first to test visiting goalkeeper Neil Parry but was denied by a flying save in the opening stages.
The Spiders were next to attack, but Ian Watt's effort was acrobatically tipped over the crossbar by Michael Andrews.
Parry was called into action again on the half-hour mark, producing a fine double save from Scott Johnston and then Wood.
Chances were at a premium in the second half and the hosts were reduced to 10 men in the 74th minute, when Paul Lunan was dismissed for his challenge on Watt.
The hosts made the numerical advantage count in the final minute, when Longworth fired home from substitute Owen Ronald's cross.
