One place the Model 3 is not on display is the Quebec City auto show which opened to the public today. Peculiar decision by Tesla, but consistent with what they did with the X in 2016. Since the QC auto show is only a one-week deal and the 3 was already at the Toronto show, I don't know why they wouldn't prefer the 3 in Quebec City this week. Or, better yet, they could have brought another 3 from the States just for the Quebec event.
January 2016: No X at the Montreal Show.
February 2016: X present at the Toronto show.
March 2016 : No X at the Quebec show.
January 2018: No 3 at the Montreal Show.
February 2016: 3 present at the Toronto show and afterwards at the Yorkdale store.
March 2016 : No 3 at the Quebec show. Nothing at the sole Tesla facility in the province, either.
