Engineer Salary in Quebec: Gross vs Net Pay

Engineers in Quebec earn a good living. But between the figure written on the job offer and the one that lands in the bank account, about a third goes missing. Here is where that share goes, discipline by discipline, based on salaries actually observed in Quebec.

What engineers earn in Quebec

Engineering is not a single job: each discipline has its own market. Job Bank publishes, for every occupation and every province, three reference points drawn from Statistics Canada's Labour Force Survey — a low, a median and a high hourly wage. Here are the three most common disciplines in Quebec, for the 2023-2024 reference period.

The word "median" deserves a second of attention. It means that half the engineers in the discipline earn less than that wage and the other half earn more. It is not an average: a handful of very high salaries does not pull it upward. On the other hand, these figures mix every level of experience and every region of Quebec — someone straight out of school and a project manager with twenty years behind them sit in the same basket.

We ran the same exercise for a police officer's salary in Quebec, where pay follows a negotiated scale rather than a market statistic.

From hourly rate to annual gross

An hourly rate only becomes an annual salary once it is multiplied by your hours. The Salarium calculator uses 37.5 hours a week over 52 weeks, or 1,950 hours a year: the most common basis for a full-time office job in Quebec.

On that basis, the civil engineer's median rate of $49.74 works out to a gross annual salary of $96,993. That is the salary the rest of this article follows, from gross to net. If your week is 35 or 40 hours, the result changes: the net salary calculator recalculates everything as soon as you change the number of hours, and the civil engineer job page shows the same calculation per hour, per week and per month.

What the deductions take out of $96,993

Five mandatory deductions apply to a Quebec employee: federal tax, Quebec tax, the Quebec Pension Plan (QPP), Employment Insurance and the Quebec Parental Insurance Plan (QPIP). Here is what they come to on that gross.

In total, close to $29,281 leaves the salary before it reaches the bank account. What is left is $67,712 net a year, or roughly $5,643 a month. The two income taxes weigh far more than the three contributions combined.

Average rate and marginal rate: two very different numbers

Two percentages describe this salary, and they are often confused.

The average rate is the share of the gross that goes to deductions, all levies taken together: 30.2% here. The marginal rate concerns only the next dollar earned — it is the share a raise would hand over to tax. It comes to 36.1%. Here is how you get there, step by step.

Start with the federal side. At $96,993, the highest portion of the income falls into the second bracket of the federal tax brackets published by the Canada Revenue Agency, taxed at 20.5%. A bracket is simply a portion of income to which a given rate applies: only the dollars sitting inside the bracket are taxed at that rate, not the whole salary.

Then comes a Quebec particularity. A Quebec resident does not pay that 20.5% in full: their federal tax is cut by 16.5%. This is the Quebec abatement, compensation for the fact that the province runs programs itself that Ottawa funds elsewhere. After that reduction, the 20.5% federal rate actually costs 17.1%.

Finally, Quebec tax. At this income level you sit in the second Quebec bracket, whose rate is 19%. The Quebec bracket thresholds are published each autumn by Quebec's Ministère des Finances: for 2026, that second bracket runs from $54,345 to $108,680.

All that is left is to add them up: 17.1% of federal tax after the abatement, plus 19% of Quebec tax, equals 36.1%. That is the rate that applies to a bonus or a raise — not the 30.2% average rate.

Past $85,000, contributions stop rising

The three social contributions do not climb forever. Each has an income ceiling beyond which it stops increasing, and an engineer at $96,993 has passed all of them.

QPP has two. The first earnings ceiling is set at $74,600 for 2026. Above it, a second contribution applies up to a second ceiling of $85,000, according to the earnings ceilings published by the Government of Canada. Past $85,000, the contribution stops growing entirely.

Employment Insurance caps out even earlier. Maximum insurable earnings are $68,900 for 2026, and the rate that applies in Quebec is 1.30% — lower than the 1.63% charged in the rest of Canada, because Quebec funds its own parental benefits. The maximum employee premium therefore comes to $895.70 for the year.

At this salary level, only the contribution to the Quebec Parental Insurance Plan keeps tracking income, at an employee rate of 0.430%.

What to keep in mind before you negotiate

• Compare offers on annual gross, never on the hourly rate alone: $44.00 an hour over 40 hours a week pays more than $49.74 an hour over 30 hours.
• A $5-an-hour gap between two offers is $9,750 gross a year on a 1,950-hour basis — about $6,230 net once the 36.1% marginal rate has been applied.
• Published medians mix every level of experience. After ten years of practice, aiming at your discipline's median means aiming at the middle of a group whose upper half you are already in.
