[3] The typeface and TTC logo were developed during the construction of Line 1 Yonge–University in the 1940s, perhaps by draughtsman Philip Butt, but the original designer has not been determined.

[6] In 2011, Dominion Modern ran an exhibit on Toronto Subway at George Brown's School of Design.

[3] This decision was made in conjunction with officially adding route numbers to the subway and RT lines.

The wayfinding team also created an overhauled version of the Subway typeface called Bloor–Yonge, which includes missing numerals (which were necessary for signage for Highway 407 station) and punctuation, as well as correcting some design issues with the existing glyphs.

Somewhat similar typefaces include Johnston (used by Transport for London), Verlag, Bernhard Gothic, Metro, Brandon Grotesque, Neutraface, and Eagle.
