Has any CFL team ever had a perfect season,?

Question

That's 18 wins in the reg season, plus 3 more in the playoffs, for a record of 20-0

Answer 1

Calgary has, but it was in a 12-game regular season in 1948, before the start of the modern Canadian Football era. They also tied a game in the playoffs (the preliminary round was a 2-game series in that year) and went on to win the Grey Cup.

But this was before the CFL was established in 1958, and since then no team has ran the table.

Answer 2

Calgary Stamps... no jk... GO STAMPS
