RREGOP factor 90 rule: unreduced retirement, examples and strategies 2026

What Is Factor 90?

Factor 90 is an eligibility criterion for unreduced retirement under the RREGOP. It is calculated by adding the member's age to their years of credited service at the time of retirement. If the total equals or exceeds 90 and the member is at least 60 years old, they qualify for their full pension with no actuarial reduction.

Factor = Age + Years of credited service >= 90 (minimum age 60)

The minimum age of 60 is an essential condition that is often overlooked. An employee aged 55 with 35 years of service reaches factor 90 (55 + 35 = 90) but cannot benefit from this rule because they are not yet 60. However, in this specific case, the 35-year service condition is met and permits unreduced retirement regardless.

Comparing the Three Unreduced Retirement Conditions

RREGOP provides three distinct conditions for unreduced pension access. The first condition met entitles the member to retire without penalty:

1. Age 61: the member reaches age 61 regardless of years of service. This is the simplest and most common condition for employees who began their public sector career after about age 32.

2. 35 years of service: the member has accumulated 35 years of credited service regardless of age (no minimum age: age 55 only applies to retirement with a reduction). This condition benefits employees who started very young.

3. Factor 90: age + years of service >= 90, with a minimum age of 60. This condition provides an exit before age 61 for employees with sufficient service. It represents a trade-off between age and seniority.

For advisors, identifying which condition will be reached first for each client is essential. This determines the optimal departure date and allows planning of service buyback or phased retirement strategies accordingly.

Real Examples of Factor 90

Example 1: age 60 + 30 years of service = 90

Nathalie, a nurse, started in the health network at age 30. At 60, she has 30 years of service: 60 + 30 = 90. She meets the factor 90 condition and the minimum age of 60. She can retire with a full pension. With an average salary of $82,000: pension = 2% x 30 x $82,000 = $49,200 per year ($4,100 per month) with no reduction.

Example 2: age 62 + 28 years of service = 90

Robert, a civil servant, started at age 34. At 62, he has 28 years of service: 62 + 28 = 90. He reaches factor 90, but he could also have retired at 61 without reduction (age condition). In his case, factor 90 provides no additional benefit since the age 61 condition was already met one year earlier. This example shows that factor 90 is primarily useful for departures between ages 60 and 61.

Example 3: age 55 + 35 years of service = 90 (special case)

Sylvie, an orderly, started at age 20. At 55, she has 35 years of service: 55 + 35 = 90. However, she does not meet the minimum age of 60 for factor 90. No problem: the 35-year service condition is met and entitles her to unreduced retirement. Pension: 2% x 35 x $75,000 = $52,500 per year. Sylvie retires at 55 with her full pension.

Example 4: age 60 + 29 years = 89 (factor not reached)

Denis, a technician, age 60, 29 years of service: 60 + 29 = 89. He is one point short of factor 90. Since each month of work adds one month of age and one month of service, he will reach it in 6 months (60.5 + 29.5 = 90). If he retires at 60, he faces a permanent reduction of 6 months x 0.5% = 3% (the reference date being the earliest unreduced date, age 60 and a half, not 61). By waiting six months, he eliminates the penalty and adds half a year of service. With an average salary of $78,000: pension at 60 = 2% x 29 x $78,000 x 0.97 = $43,883; pension at 60 and a half = 2% x 29.5 x $78,000 = $46,020. That is $2,137 more per year, for life.

Strategies to Reach Factor 90 Faster

Service buyback

Service buyback adds years to the service count and accelerates reaching factor 90. A 2-year buyback for an employee aged 58 with 26 years of service (current factor 84) would allow reaching factor 90 at age 60 (60 + 30 = 90) instead of waiting until 61 (without the buyback, they would only have 60 + 28 = 88 at 60). A buyback paid with personal funds is tax-deductible (in full for post-1989 service) and the implicit return is generally excellent.

Phased retirement

During phased retirement (a 1- to 5-year agreement with the employer, with mandatory retirement at the end), service continues to accumulate on a full-time basis even though the employee works only part of their regular schedule (at least 40%). This allows progression toward factor 90 at the same rate as a full-time employee while enjoying a reduced workload.

Check the 90 contributory days added

When the pension is calculated, Retraite Québec automatically adds up to 90 contributory days, for both eligibility and the pension calculation (s. 74), to fill absences without pay before January 1, 2011 or related to maternity, paternity, parental or adoption leave. These days can make a difference for a member close to factor 90. It is not a bank the employee uses at will: the advisor should check with the client, using the Retraite Québec statement, whether such absences exist.

Long-term planning

Ideally, factor 90 planning begins several years before the expected retirement date. The advisor should request the participation statement from Retraite Quebec and identify buyback-eligible periods, service gaps, and available options to maximize recognized years. The earlier planning begins, the more options are available and the less costly they tend to be.

Common Pitfalls with Factor 90

The most common pitfall is forgetting the minimum age of 60. A member aged 58 with 32 years of service (factor 90) cannot benefit from this rule and must either wait until 60 or check if they reach 35 years of service before that date.

Another pitfall is confusing credited years of service with years of employment with the employer. Unpaid leave periods that were not bought back, part-time periods (counted pro rata), and service interruptions can reduce recognized years. Always refer to the official Retraite Quebec participation statement.

Finally, some clients confuse RREGOP's factor 90 with similar rules in other plans (RRPE, federal pension plan). Conditions vary between plans and are not interchangeable. The advisor must verify the specific plan before applying this rule.
