MCPT is William Lyon Mackenzie C.I.'s computer science council, where we host weekly lessons for both competitive programming and general computer science topics. Additionally, we host monthly team-based competitions, dubbed the LCC, Lyon's Computing Competition, modelled after the CCC.

We are EXCITED to be hosting a city-wide team-based mock Canadian Computer Competition on February 12, 2026! This will give students a chance to practice their computer programming skills and prepare for the actual CCC. Prior to COVID, MCPT hosted annual in-person competitions, and we're pleased to announce that this will be our first in-person competition since 2019!
