If it is contract job, and the employer pay you a lump sum wage that includes everything, like what you have got, the nature of your employment is like self-employed. You report your income at year end. You can deduct your business expenses from your income. You have to pay your share of CPP (Canadian Pension Plan contribution). It is optional to pay EI. If you pay EI, you can enjoy EI benefit. There is a form with guide at Canada Custom & Revenue Agency (CCRA) called "Statement of Professional Activities". Go find the guide and read it.
If it is employment nature. Your employer MUST WITHHOLD your CPP contribution, EI premium, and your estimated income tax from each pay and submit them to CCRA every month. Your employer also has to contribute CPP for you, pay 140% of EI you pay, plus Workplace Safety Insurance for you. It is illegal to just give you wage but contribute nothing of CPP, EI, and WISB for you.
That might be the reason that some employers are reluctant to hire people as employees.
