Canada’s Liberal government is poised to pass controversial legislation on Friday that aims to kick-start “nation building” infrastructure projects but has received widespread pushback from Indigenous communities over fears it tramples on their constitutional rights.

On its final day of sitting before breaking for summer, parliament is expected to vote on Bill C-5. The legislation promised by Mark Carney, the prime minister, during the federal election, is meant to strengthen Canada’s economy amid a trade war launched by Donald Trump.

The bill removes interprovincial trade barriers and aims to prioritize infrastructure projects, such as energy pipelines and mines deemed to be in the national interest.
