Survival Job - How much and how soon?

Dear friends,

I am planning to move to Canada soon. Since I am a mechanical engineer so won’t be able to start my professional career right away.

It’s because I will have to acquire PE first, which may take a year or so. So during that period I shall be requiring a survival job which could help me to run my kitchen at least.

What kind of jobs are available in Toronto that a new immigrant can start with and what are the hourly wages.

Can a person manage to make around 3000 CAD monthly.

And how quickly one can get these kind of jobs.

Please note that I shall be moving with my wife and three kids.

Thanks
