Scarborough Subway Extension - Tunnel Boring Machine Naming Contest - Voting

Be a part of transit history! Here’s your chance to make your mark on a project that will transform how we travel across the region.

The three-stop Scarborough Subway Extension will extend the TTC’s Line 2 subway service nearly eight kilometres farther into Scarborough and provide seamless, reliable rapid transit to the people who live, work and play in this bustling part of the city. It will bring 38,000 more people and 34,000 more jobs within walking distance to transit.

Now, we’re inviting you to help us name the machine that will dig the tunnel for this important project! It's called a "tunnel boring machine" (TBM) and, with a 12-metre diameter, it will be the biggest of its kind in Toronto's transit history.

With the TBM expected to arrive on site in January 2022, there's a bit of time to get creative.

The winner of the naming contest will have the chance to participate in a photo-op before the TBM begins digging.

The contest will take place in two phases. Here's how it will work:

Phase 1 (closed)

Starting October 19, submit your name ideas using the submission form below. Let us know why you picked that name or what it means to you.

Looking for inspiration? Think about local landmarks, special places, local history – something important to you!

Name submissions closed at 4 PM on November 18.

Phase 2 (closed)

The TBM naming contest has now closed. Thanks for participating! Check back in January to find out the winning name.
