Toronto FC won the competition for the third consecutive year and qualified for the 2019 CONCACAF Champions League.

The 2018 edition saw the invitation of the champions of League1 Ontario (L1O) and Première Ligue de soccer du Québec (PLSQ).

FC Edmonton suspended operations and did not take part in the Championship this year.

As a result, a new format was adopted which saw the L1O and PLSQ champions, the Oakville Blue Devils and A.S. Blainville, enter in a new first qualifying round.

Statistics include previous incarnations of the Montreal Impact and Vancouver Whitecaps.
