2018 Smellfie Contest

The Enbridge Gas smellfie booth was at popular events across Ontario throughout 2018. We had a great time educating everyone about natural gas safety. We asked people to take a picture of their face reacting to the awful smell of natural gas - this was their Smellfie. The contest* ended on December 31, 2018. Thank you to everyone that entered. The ten winners of $500 have been drawn and will be announced soon.

Entries are posted in our Flickr photo gallery.

*Winners were chosen through a random draw. Read the full 2018 Smellfie Contest Rules and Regulations.
