A one-way economy flight from Toronto to India is about $700. One billion dollars would pay for 1.4 million Indians to remigrate. There are between 2 and 3 million Indians in Canada.
Currently there are about 17k CBSA officers. A CBSA officer makes about $100k, so $1B would be enough to hire 10,000 of them, increasing the workforce by about a third, with the new hires forming a dedicated remigration branch.
The federal government spends more than $1 BILLION dollars a year providing free healthcare for "asylum claimants" (illegal immigrants) through the IFHP.
How many Remigration Enforcement Agents does that buy?
How many flights to Punjab does that pay for?
That's just one program!
