Don't forget to account for the health care package that includes dental..and this is family coverage. Also the company contribution to the pension plan (4%)
Add to this the Per Diem (arguably not a valid factor) and also the Incentive Pay which usually runs 75 - 125/day.
Most CHC guys in Nigeria would be clearing in excess of 100,000 CDN and this 80% tax free (for OETC eligible Canadians)
It's still not what the job deserves..but more competitive than first appears.
