In Alberta, the minimum age for an executor is 18 and there is no maximum age. That being said, an executor still going through puberty (for me, I think I was 30) or an executor with firsthand memories of the “Great War” may be too young or too old.

A good executor is often someone your age or younger. The reason for this is simple. You want to maximize the likelihood that your executor will be alive after you have died. If you are still in your 20s, 30s, or 40s, an older executor may not be a problem, but you will eventually want to change your executor if you pick someone older.

Given the desirability of choosing an executor your age or younger, it is easy to see why spouses and adult children typically make good executors. A spouse is often approximately your age. A child is necessarily younger than you, typically by at least two decades.
