Canadians could find out tomorrow how the federal government will respond to the staggering 187 Senate recommended amendments to Bill C-69.
Bill C-69 would revamp the way the Feds evaluate major infrastructure projects such as oil pipelines.

He lashed out at six premiers representing five conservative provincial governments and a territory who want Ottawa to accept every single amendment or risk a constitutional crisis.
Trudeau is accusing them of playing games with national unity.
