Transportation is 28% of CO2 emissions in Canada.

Of that, road transportation is about two thirds (or about 19%); the remainder is primarily air and rail.
That said, I very much do agree with reducing our GHG emissions. (Note that we should also eat less beef, cows emit massive amounts of methane, which is far worse for the climate than CO2.)
Our region is not the same as Canada:

Page 12, regionally our transportation emissions are 49% of our total emissions in 2015.
Yes, methane is a more potent green house gas, but it's more complex than that, it breaks down in the atmosphere far quicker than CO2, so the long term steady state result is more complex.
