Saan ka nga ulit sa Canada, peej06?
EDIT: Ayyy, duhhh, Calgary ka pala. My sister lives there.
If you have not started school yet, you are not allowed to work fulltime OR part time. So start working when you officially start school. Mahirap na magkaproblema.
My advice to you - when you are starting work is to go to the stores around your community and personally hand in your resume. I got my first job that way (in No Frills) ... I now work in Loblaws
Most of the part-time jobs are advertised online, especially sa mga grocery stores and shops - off the top of my head, these are the companies you can apply to online:
Walmart, Loblaws, Shoppers Drug Mart, Cineplex / Scene, McDonald's
Yung mga ok for walk-in: No Frills, Dollarama, Metro
Also, you will need to um ....
simplify your resume if you have professional experience back home. This means tanggalin mo sa job descriptions mo yung high-level tasks for example, if you are applying for a part-time job. You can even simplify your job title (ex. Marketing Manager to Marketing Supervisor ....)
Two, always write a cover letter along with your resume or else it won't be noticed or it will be thrown away.
Three, when looking for a job, make a plan. Everyday, make a list of stores you want to submit to and then make a travel plan. Yes, ganun katindi.
Lastly, don't be discouraged if at first no one calls you. Ganun talaga dahil nag-aadjust ka pa sa bagong bayan lol but they will come. It took me almost two months to find a good job. Nobody called me at first, medyo nakakadiscourage, pero once may tumawag na, sunod-sunod na ang tumawag, I even had to turn a few jobs down lol. I started working in October 2015 and have been working steadily since!
Good luck!
