You're speaking out of your ass with no proof. All politicians cater to the wealthy who want mass immigration to drive down wages. Immigration isn't a right vs left issue, its a rich vs poor issue.
Alberta is so anti-immigrant they are the only province with a dedicated immigration stream for law enforcement, they want to be policed by immigrants.

Danielle Smith could announce that Alberta is accepting 1 million new immigrants today, slash that number to 900k after "consulting with Albertans", and people like you would eat it up as evidence that Alberta is anti-immigrant.
