TransLink is a very flawed system.
The system was taken away from local governments as a result of local mayors being originally opposed to the Canada Line being prioritized over the line to Coquitlam. Then-minister Kevin Falcon removed the mayors from control of TransLink and subsequently set up the mayors' council. The council has no real powers in regard to the running of the system, aside from two of the mayors who are selected by weighted vote to sit on the board. As a result, the two largest cities have used their weighted vote to be on the board.
It's extremely frustrating. There is a consistent demand from the mayors in the region to regain control of TransLink and that the government change the system of governance that's been put in place. It's been a source of great frustration over the years and was considered to be vengeance for the mayors having opposed a provincial plan to prioritize the Canada Line for the Olympics.
