Given an elliptic curve E over a function field K = ℚ(T₁,...,Tₙ), we study the behavior of the canonical height $ĥ_{E_ω}$ of the specialized elliptic curve $E_ω$ with respect to the height of ω ∈ ℚⁿ. We prove that there exists a uniform nonzero lower bound for the average of the quotient $(ĥ_{E_ω}(P_ω))/h(ω)$ over all nontorsion P ∈ E(K).
