The claimant sought entitlement to social work services, HST on treatment plans, and the cost of CAT assessments. Adjudicator Chakravarti held that the limitation period applied to the social work services because the denial of the proposed rate was clear and unequivocal. Section 7 of the LAT Act did not apply because the claimant did not provide any details as to why the dispute was brought outside the limitation period. The limitation period did not apply to the HST claim because the insurer provided contradictory reasons in the denial letter. The limitation period did not apply to the CAT assessments either because the denial letter only indicated that the insurer had not made a decision regarding the proposed costs.
