Hey Ottawans đź‘‹
Do you know where I can find the origin of your street names? I want to know the story behind “Data Centre Rd” and “Tremblay Rd”

Yo les Ottaviens•iennes 👋
Savez-vous où je peux trouver l’origine de votre toponymie? Je veux connaître l’histoire derrière « ch. Data Centre » et « ch. Tremblay »
@EdwinG Thsi does not contain your answer on Tremblay Rd, but could give you pointers

Image is from 1958 prior to construction of the "union" train station. The 417 was still being built. (You can see the exchange at 417/St-Laurant beilng built on right. And Tremblay had its onw bridge across the river to connect to Hurdman St. (in pioc 2, you can see the newly built but not yet open 417 bridge. Street predates train station by long time.
