Depending on your province of residence, ministry of health coverage could be available. It is always best to first discuss this type of funding with your physician—a referral to a genetics (or other) specialist may be required.
In some provinces, WES test costs are reimbursed only when ordered by a qualified geneticist. This is usually the case in Ontario, for example. Once the geneticist gains approval via a Ministry of Health and Long-Term Care letter, he/she can attach the Ministry’s approval letter to the requisition.
