Here's the historical part about the creation of the Senior 30' division

. I'm in no way criticizing the decisions that were taken but just presenting how it happened (from what I remember). Alberta was the first Province to introduce that division. Their first champion was crowned in 1986 and they set the minimum age to play at...65.
At the Canadian Championships, the division was introduced in 1988, the year incidentally Alberta (Calgary) was hosting it. I remember there was a hot discussion, possibly in 1987 or 1988, when came the time to officially create the Senior 30' division at the Canadian level. Ontario wanted to set the minimum at 70 years old, like in the US, but Alberta wanted it at 65 because they had been going for two years and were afraid they would lose a fair amount of members. So it was finally decided to go for 65.
Most provinces started to crown a Senior 30' champion after that, using the same age limit (BC - 1989, Sask - 1990), except for Ontario (1991) who maintained the minimum age at 70 for many years (maybe they still do

).
Of course, changing the age minimum from 65 to 70 these days would hurt a lot more than back in 1988. For instance, 50% of Alberta's membership is now made of Senior 30' pitchers! See stats here:

Andre.
P.S.: I could have said that our long winters are rough on our men (too much snow shoveling). That's why they are allowed to move up to 30' earlier
