Any application form has space for prior job experiences but somehow, every working person in Canada also started their first job without any prior experience. If you come from a foreign country, you fill in your prior foreign experiences and if you never had a job before, you put nothing.
You will usually find factory jobs in factories. If you find no job ads where you can apply, try to go into industrial neighbourhoods and see if you see help wanted signs. Even when you don't, it does not hurt to go to the office and leave your application. Sometimes you get lucky and you end up with a job out of it.
A good example, I know a woman who moved to Edmonton. She had lived a sheltered life and at age 30, her CV was literally empty but she needed a job. She started applying. Of course she did not get all the jobs she applied for. She did call centre for short time and hated it. Then she got a job as a waitress but she had to work 3 hours during lunch time and then had 3 hours off and then had to work another 6 hours in the evening. It was not a very convenient working day. Then she got a job in a hotel reception. This one was not bad but it didn't pay very well. Then she got a job in a department store and this one was much better. You see, each of the crappy jobs both provided money in the piggy bank as well as the much needed job experience and she never stopped trying which resulted in landing better and better jobs all the time. That just an idea of how you can do it.
