Under the umbrella of Canadian Independent Masters Swimmer (CIMS), Masters Swimming Ontario (MSO) and Masters Swimming Manitoba (MSM) joined efforts to prepare the coaching materials and reference links below. These materials can be used to help plan and enrich practices, and to give swimmers of all abilities good foundations to improve strokes and swimming efficiency.
While continuous learning is strongly encouraged, coaching certification is not required by CIMS, MSO or MSM. Links are provided below to organizations offering formal training and certification.
