We prove that the topological conjugacy relation on pointed Cantor minimal systems is Borel bireducible with the Borel equivalence relation $\\Delta_{\\mathbb{R}}^+$ on $\\mathbb{R}^{\\mathbb{N}}$ defined by $x \\Delta_{\\mathbb{R}}^+ y \\Leftrightarrow \\{x_i:i \\in \\mathbb{N}\\}=\\{y_i:i \\in \\mathbb{N}\\}$. Moreover, we show that $\\Delta_{\\mathbb{R}}^+$ is a lower bound for the Borel complexity of topological conjugacy of Cantor minimal systems.
