If there is such a risk, it has always been there. People aren't forced to do blood screenings at immigration, so we are relying on their own testimony and visible appearance of vitality as indicators of health.
When Ellis Island was open, you did have to undergo a health check, if you had, TB, conjunctivitis, etc., you were denied access & it should be that way now.....
What's this 'we' crap, are you a U.S. citizen, or a Canadian?......
British Columbia is already over-run with immigrants, now you would add diseased ones as well?.....
If they are so valuable, Canada can take them, they need the help....
If a doctor does not have accredidation from a U.S. recognized school, their MD degree is worthless here, that's why you see Pakis driving cab in NYC....
Besides we already have too many lawyers here anyway....:lol:
Immigration?... Fine....
Diseased immigration?.... NO THANKS!
Besides that, you are using exceptional examples, the average diseased immigrant will likely be unskilled.....
