Great place to start but nowhere for senior employees to go.
Pros
Excellent pay. Environmental consulting company with a strong science base and good engineers too (not the typical engineering company with a few scientists tacked on). "Big Science". Rescan takes on large, complex projects with multimillion dollar budgets. No running around doing silly little backyard projects.
Cons
Projects lack diversity. It's 90% mining in Northern Canada with the odd international job. No room for seniors to grow. Executive management is young, so you will remain a senior scientist or project manager forever if you wait for them to retire. Very poor work/life balance - no flexibility in hours, telecommuting not allowed, only 3 weeks vacation per year. CEO does not trust his employees - no working from home, must sign in/out of the building just to get a coffee.
