Don't do it.
Cons: Long hours, excessive labor, poor wages, poor benefits
I took this job to build a work history in Canada, working for Dollarama was the biggest mistake of my life.
If you like pain, no support. Poor management, no resources, being consistently understaffed for months at a time, ten cent raises,working every holiday and excessive blackout periods for vacations then Dollarama is the place for you.
