Ethics commissioner Mary Dawson will examine whether Health Minister Jane Philpott violated the Conflict of Interest Act in her use of a high−end car service owned by a Liberal supporter.

Dawson’s probe — set to focus on a section of the act pertaining to "preferential treatment" — comes after Conservative health critic Colin Carrie wrote to the commissioner about Philpott spending $1,700 on a single day’s car service and more than $1,900 on another day.

Philpott’s office says it has received notice from the commissioner and will fully co−operate with Dawson.

Philpott announced last Thursday she would repay the cost of these trips, totalling just over $3,700, and she apologized for incurring the expenses.
