In 1949, Lehner showed that certain coefficients of the modular invariant j(tau) are divisible by high powers of small primes. Kolberg refined Lehner's results and proved congruences for these coefficients modulo high powers of these primes. We extend Lehner's and Kolberg's work to the elements of a canonical basis for the space of weight 0 weakly holomorphic modular forms.
