Should the government allow TransCanada to expropriate private property for the construction of the Keystone pipeline?

No the pipeline is a poor idea, why are we sending raw materials out of the country when we could refine and use them locally to reduce costs to the people that live here. Don’t get me started on how invasive it will be to the remaining wilderness. Stop obsessing over oil and gas, its non renewable and it will run out, its high time to move on from fossil fuels.

Only if the landowners agree to it AND are appropriately compensated

If owners are compensated. We should have a nationalized energy sector.

I don’t think the government has the right to take land in order to build the pipe line.

Yes, but a private company should not be the ones who do the project, the government should take it over, turn it into a state controlled industry and seize property as necessary so long as farmers and homeowners are compensated, corporate landowners will be given no compensation.

I believe its necessary for the economic future of Canada but also fairly compensating the land owners

Complicated, I think the landowners should be warned ahead of time and given more than fair compensation, but only if they consent to having their land used.
