B-C government will be allowed to intervene in a legal fight against the Trans Mountain pipeline expansion, with some conditions. Ottawa has approved the 7.4-billion-dollar project that would triple the capacity of the Alberta-to-B-C pipeline and increase tanker traffic from the Vancouver area to the southern part of Vancouver Island. Several First Nations and municipalities filed legal challenges against the project while the N-D-P government applied to be an intervener after missing the initial deadline ahead of May’s election. The Federal Court of Appeal ruling says the province can be involved at October’s hearings but cannot introduce new issues or evidence.
