I was able to get some viewership numbers for the Brier final weekend:
The tiebreaker between Quebec and Manitoba: 271,000
The 1 vs. 2 game between Ontario and Alberta: 587,000 (1,000 more than the game between the same teams the night before)
The Brier final (drum roll please): 873,000
Interesting to note that the Scotties final outdrew the Brier final.
