First, you need an immigrant visa. It will take from 18 months to three years to get. Do not, under any circumstances let any immigration agent take your money. They promise a lot and cannot do anything different from what you do yourself, at no cost, or for very little. Apply here:
Print out ALL documents that apply to your visa and fill in every single line and word asked for BEFORE you submit the package to the office listed for your country. Anything left incomplete will delay your visa at least one month at a time. I repeat, fill in EVERYTHING you can before you send away the package.
Civil Engineering is a "regulated" profession. You must have a valid degree from a pre-recognized university to be accepted as a " Professional Engineer". After acceptance you have to work for five years in a qualified job, then you get your certificate. - And then you will easily earn $ 100 000 or more per year.

If you have only a Technologists degree, three years of university or less you will need to study and sit for all the exams at the Professional Engineers Association. (They are different for each Province - I gave you only one, Ontario) This is not impossible - I sat for many when I first came to Canada as a young Engineer, years ago.
Civil Engineering jobs are common. There is a lot of construction in various parts of Canada now so you should be able to find a position but - only AFTER you have your visa, have arrived in Canada and have your Social Insurance Number (tax number) in your hand. Don't bother looking for jobs before then, no one will even talk to you.
Salaries? Who can tell? You will have to start at a low level, if you don't have any previous Canadian work experience and work your way up. - You won't live the rich man's (woman's) life for years to come. You may start at $ 13.00 - $ 15.00 per hour = $ 26,000 - $ 30 000 per year - NOT a rich salary when even the smallest apartment will cost $ 1 000 per month.
But, a good man (or woman) will rise to the top. There is no discrimination of any kind in Canada, you are only judged on your capabilities.
Good luck with your future career.
