You’re right to question the tension here—Alberta’s Employment Standards Code requires that employees be paid within 10 consecutive days after the end of each pay period. This effectively limits how far “in arrears” an employer can operate. With a semi-monthly schedule (e.g., pay periods ending on the 15th and last day of the month), organizations can still pay in arrears, but only by a few days—not weeks. In practice, many employers set a short lag (e.g., 3–7 days) between the period end and pay date to allow for payroll processing while staying within the 10-day rule. A longer arrears model (like holding a full extra pay cycle behind) would not be compliant in Alberta.

Biweekly payroll is often preferred because it naturally aligns better with the 10-day requirement while giving payroll teams a predictable processing window (e.g., period ends on a Friday, pay the following week). It’s true this increases payroll frequency compared to semi-monthly, but it reduces compliance risk and administrative strain caused by tight turnaround times. That said, semi-monthly can still work compliantly—you just need efficient cutoffs, possibly estimating and adjusting variable earnings, and tight payroll processing timelines.

For a short-term (90-day) full-time contract, hourly is often the cleaner and lower-risk approach—especially if the role may involve any variability in hours, overtime, or schedule changes. Hourly pay ensures you’re automatically compliant with Alberta’s rules around overtime, general holiday pay, and accurate earnings tracking without needing to “reverse engineer” an equivalent hourly rate from a salary. It also aligns well with paying vacation pay out each period, which is common for short-term or temporary roles and avoids accrual/termination payout complexities at the end of the contract.

That said, salary can still make sense if the employee will work consistent, predictable hours with little to no overtime and you want a simpler, fixed compensation structure. The hesitation around salary for short contracts usually comes from administrative edge cases—prorating partial periods, ensuring compliance with minimum standards for hours worked, and handling any overtime that might arise. If those risks are minimal, salary isn’t inherently wrong—it just requires tighter controls.

In your case, hourly with vacation paid out semi-monthly is likely the most straightforward and defensible option. It keeps everything transparent, reduces compliance friction, and avoids cleanup at the end of the 90-day term. Salary could work, but it doesn’t offer a clear advantage unless there’s a strong operational reason for it.
