For $g\in \mathbb{ N}$, let $G=\Sp(2g,\mathbb{ Z})$ be the integral symplectic group and $S(g)$ be the set of all positive integers which can occur as the order of an element in $G$. In this paper, we show that $S(g)$ is a bounded subset of $\mathbb{ R}$ for all positive integers $g$. We also study the growth of the functions $f(g)=|S(g)|$, and $h(g)=max\{ m\in \mathbb{ N}\mid m\in S(g)\}$ and show that they have at least exponential growth.
