Residents in the Greater Toronto Area may not have to worry about a missed parcel delivery again.

High-tech parcel pickup stations designed by a Waterloo-based company were unveiled this week at five GO Transit locations.

The bright green kiosks — called BufferBox — offer people an easy-to-use and secure way to receive packages at any time.

Customers will be notified via email when their item is available and will be provided with a unique PIN code to retrieve their package.

Each unit contains 20 compartments.

BufferBox Inc. co-founder Mike McCauley says the kiosks allow users to pick up their items en route, eliminating the frustration of having to travel to the post office, or potentially have their parcels stolen when left at the doorstep.

"It reverses the currently delivery model, where parcels wait for consumers instead of consumers waiting at home for parcels," said McCauley, who believes BufferBoxes could potentially eliminate home delivery in the future.

GO Transit riders will now be able to pick up their parcels through the self-serve system at Union Station, and the Burlington, Oakville, Port Credit and Clarkson stations.

McCauley — a University of Waterloo graduate — first tested the parcel delivery kiosk at the university's Student Life Centre.

While the main focus is to build out the GO Transit network, McCauley said the company is also experimenting with other locations where there is high pedestrian traffic, including convenience and grocery stores.

The company says it will install 21 BufferBoxes in the Greater Toronto and Hamilton areas by the end of this year, and about 100 more by the end of 2013.

Users can try the service for free until the end of the year. McCauley estimates the pricing to range from $3 to $5 per parcel after that.
