If you suffer from Celiac Disease – you can definitely submit a claim for the incremental costs associated with the purchase of GF products!
However, for us to process the claim, we need the following:
Letter from a Medical Practitioner confirming the person the GF products are for suffers from Celiac Disease and therefore requires the GF products as a result of the disease; and
The incremental cost calculation between the cost of the GF products claimed and the cost of a similar non-GF product
You can review the CRA's guidelines for Gluten Free expenses on their website, including an example of how to calculate that incremental cost.
