Part I of this paper deals with two-dimensional canonical systems
y′(x) = yJH(x)y(x), x ∈ (a, b), whose Hamiltonian H is non-negative and locally integrable, and where Weyl´s limit point case takes place at both endpoints a and b.
We investigate a class of such systems defined by growth restrictions on H towards a.
