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 (open)

A judging panel will create a short list from all the submissions received. The judging panel will choose names based on relevance, rationale and significance to the project and area.

We’ll then invite you to come back and vote on the top picks.

Voting will close on December 22, 2021.

Phase 2 is now open!

Vote for your favourite entry from the shortlisted names, selected for their creativity, relevance and significance to the project area. Thanks to everyone who submitted their ideas. Read about the rationales behind the names and vote for your favourite below.

  • Scar-burrow - "I like to think of people moving around in subways and LRTs like little critters passing through burrows under the city."
  • Diggy Scardust - "It is a riff on Ziggy Stardust. Diggy because it is a digging machine and "Scar"dust because it is digging through the Scarborough earth and dust."
  • Scarbie SX – "An abbreviation for Scarborough Subway Extension."
  • Elizabeth - "Named after Elizabeth Simcoe, who named the area "Scarborough" after the limestone Scarborough Bluffs reminded her of her hometown of Scarborough, North Yorkshire, UK."
  • Rouge - "In honour of the major watercourse in the east end of Toronto, the Rouge River. Rouge is the French word for red which is the traditional colour of the Canadian flag and the TTC."
