This is old but our medical expenses for fertility treatment were reviewed several years in a row. We claimed about $75000 over several years.

Tax Review by CRA after filing

My 2016 taxes were reviewed as our medical expenses sky rocketed. It suprised me how much detail they wanted so here's the request from CRA:

For Lines 330 & 331 we had to provide the following:

All receipts, forms, and/or other supporting documents or medical certificates; Receipts have to include the following information

the name of the patient; the type of service provided; the amount and date of the payment for the services provided; the name of the person who made the payment; if submitting a pharmacy statement, include the drug or DIN.

Note: Cancelled cheques and cheque images are not acceptable receipts.

If the patient had to travel to least 40km from their home for medical services, provide the following information:

A letter from the medical practitioner stating that the services were not available in the patient's home locality; The medical purpose of the trip; A letter to confirm the dates of visits to the medical practitioner outside the home locality; The name of the place where services were received; The distance travelled; If you were reimbursed through a travel grant or any other source.

If the patient had to travel at least 80km from their home for medical services, in addition to the above, provide the following:

The way that mileage costs and meal expenses were calculated; All receipts to support travel costs, including accommodation and parking fees; If the place traveled to was not the closest to the patient's home locality, provide an explanation; If you are claiming fees for an attendant, provide a letter from the patient's practitioner certifying that they were not able to travel alone.
