From article: "Mr. Falcon (said) the BC Libs) got throttled in Metro Vancouver because (they) spent too much time playing politics around transportation issues (see: picking fights with Metro mayors over funding)"

The Metro mayors were the ones picking fights... 

During 2011 to 2017, the BC Libs were entirely reasonable & responsible  in their expectations-
 especially the  requirement for all new categories (sources) of Transit funding that are proposed by the MC- to be approved by voters (via referenda).

If anything, the BC Libs were far too limp wristed &  deferential to the MC during the last 6-yrs...

History shows unequivocally that when Metro Vancouver's civic politicians are allowed to have final say, and veto power over the region's public transit planning & decision-making, grievously bad decisions &  irreparable harms are the results:
