"The overwhelming majority of Canadians agree with Leitch in terms of her proposal for a stronger screening processes..."  
Where is your evidence?  There was one poll that said a majority (of those questioned) were concerned about immigration being too high.  That is a far cry from an "overwhelming majority" agreeing with Leitch's cultural values test.
Abacus reports a plurality of millennials agrees with the Liberals approach to immigration, that millennials feel not enough is being done to support minorities in Canada.  Sure doesn't sound like they agree with Leitch.
