Drinking Water Testing (Certificate of Potability for Mortgage Purposes)
The Public Health Laboratories Branch of the Ministry of Health and Long-Term Care provides routine drinking water testing for Ontarians who have their own source of drinking water (e.g. a well) that serves a single household.
The Ministry will provide a
certificate of potability for mortgage
purposes for the sale of a property. To
ensure the smooth completion of real
estate transactions, it is important that
all parties are aware of the timelines
involved with drinking water testing.
What do I have to do?
2. Test reports are mailed to the return address that appears on the submission form or, if requested, the report can be picked up at the laboratory with photo identification. If the submitter (i.e. the person whose name appears on the submission form) wishes to have the report picked up by another person (e.g. their real estate representative), a waiver must be signed by the submitter. Test reports will not be faxed.
3. To ensure that drinking water testing does not delay the completion of real estate transactions (where a certificate of potability is needed for mortgage purposes), the Ministry suggests that the client submit a sample no later than two weeks prior to the anticipated date of closing. It may be advisable to submit a sample for testing as soon as a property is listed for sale, but it should be confirmed that the interval between testing and closing is acceptable to the lender.
