According to a release, the federal Competition Bureau says its investigation found that consumers ended up paying more than was advertised on the DoorDash website and mobile applications due to additional “mandatory fees at checkout.”

The bureau says this practice is commonly known as “drip pricing,” and calls it “deceptive” because the process lacks transparency.

In some cases, the bureau says the additional “fees” may be misclassified to customers as “taxes.”

“Parliament has made it clear that businesses must not engage in drip pricing by advertising unattainable prices and then adding mandatory fees,” commissioner of competition Matthew Boswell said in a statement.
