It wasn't the "entire CN rail network" (instead it was the Eastern Canada segment, comprising maybe 15% of CN's network). They don't claim that rail carries three times more than trucks do, but instead simply note that one rail car carries as much as three trucks.

And the blockade lasted approximately 2-3 weeks. Not sure what you mean by "after almost a year".

But let's be clear -- most of Canada was enraged about that. It was hugely expensive to Trudeau politically, and was a tenterhooks [edit - thank you fennec] situation because of the aboriginal file. Yet most of Canada absolutely wanted a stronger response and it hurt Trudeau in the election.

I honestly don't get these "but the rail blockade" or "but some BLM protest in some US city" responses.
