You can't work with your tourist visa. you have to apply for work permit. you are eligible to apply
1. if your spouse is a student or doing a full time NOC 0, A or B job under work permit
OR
2. You are a full time student in Canada for several months
OR
3. if you have completed a degree (there are other conditions) in Canada, you may be eligible for post graduate work permit.
OR
4. if a company sponsors you and help you to get a work permit
Hope this helps.
