Not too far off what Post #2 and #3 suggested.
Mid to high $30k's as a base salary based on somewhere between 70 to 75 hours per month. Throw in per diems and a bit of OT and your T4 might read around the $44-$50k for the year.
Take home pay and quality of life will depend on where you get based and whether you decide to commute or not. A Year 1 FO salary working and living in Calgary is fairly different from the same salary living and working in Toronto.
