NAFTA Visa, Health Coverage in CA

If one has a NAFTA visa to work in Canada what does one do for health
insurance? Do you get a provincial health card? I'm guessing that if
it were the other direction then the US company would provide coverage
under it's health plan as part of the standard employee benefit
package.
I've got insurance coverage from the states, but it will only
reimburse. So, i'd have to out of pocket everything, send off forms
and wait to get a check. not very appealing.
Also, how do tax issues work? I imagine i'll be paying taxes in
Canada.
seen a lot of info on the CIC web site about getting a visa, but
nothing about what happens after. something like "5 things you need to
know/do/consider after getting a nafta visa" would be nice. or maybe
it's there and i just missed it?

thx
