CPKC Arbitration Has a 99-Day CN Precedent
27.08.2026
CANADA: CPKC signal and communications workers are back on the job, but the CPKC arbitration process expected to resolve their outstanding contract dispute still has no publicly identified arbitrator, timetable or disclosed scope.

CPKC said on Aug. 21 that the International Brotherhood of Electrical Workers Canadian Signals and Communications System Council No. 11 had agreed to enter binding arbitration, ending the strike that began May 31, with roughly 300 employees welcomed back beginning Monday morning, Aug. 24. The announcement runs to three sentences of substance and says nothing about what the arbitrator is being asked to settle.
Don’t miss… CPKC and IBEW Binding Arbitration Agreement Ends Strike
CN announced its arbitration result 99 days after the agreement
The nearest reference point is CN. On July 4, 2022, CN announced that the IBEW had agreed to binding arbitration; the strike ended at 00:01 EDT the next day and signals and communications employees returned at 07:00 EDT on July 6. The terms arrived on Oct. 11, 2022: a three-year agreement retroactive to Jan. 1, 2022 and running to Dec. 31, 2024, carrying a 3% wage increase in each of those years. The gap between the arbitration deal and the announced terms works out to 99 days, a figure derived from the two dates rather than stated in either announcement.
| Parameter | CN–IBEW, 2022 | CPKC–IBEW, 2026 |
|---|---|---|
| Employees covered | About 750 | About 300 |
| Arbitration agreed | July 4, 2022 | Aug. 21, 2026 |
| Strike ended | 00:01 EDT, July 5, 2022 | Effective Aug. 24, 2026, according to CPKC |
| Back at work | 07:00 EDT, July 6, 2022 | Monday morning, Aug. 24, 2026 |
| Terms announced | Oct. 11, 2022 | Not announced |
| Wage outcome | 3% a year, 2022 through 2024 | Not disclosed |
| Deal to terms | 99 days | Open |
CPKC called for arbitration on day one; the union accepted 82 days later
The company was not neutral about the route. In its May 31 release, issued the day the strike started at 08:00 MDT, CPKC said it had implemented contingency plans and encouraged IBEW to end the strike and accept binding arbitration. The union accepted that route on Aug. 21, 82 elapsed days after the strike began. Aug. 21 was the 83rd calendar day of the stoppage when May 31 is counted as day one.
What happened in between included a vote. On Aug. 14 the union reported that 287 members took part, a 97% turnout, and 256 of them rejected CPKC’s latest offer, as reported by Nelson Star. An arbitrated outcome is settled by a third party instead; CN’s 2022 announcement presented the terms as concluded and does not mention a ratification vote.
The arbitrator, the scope and the deadline remain undisclosed
CPKC has not publicly identified the arbitrator, published a hearing schedule or set out which bargaining issues were submitted to arbitration. The union’s previously stated concerns included pay, expenses, on-call obligations and scheduling, but the publicly available announcements do not establish whether all of those issues are within the arbitrator’s mandate. IBEW’s 19 complaints concerning replacement workers were pending separately before the Canada Industrial Relations Board, which had heard two of them as of mid-August, according to the Nelson Star account. In an Aug. 21 statement, IBEW Council No. 11 said delays in the Board proceedings contributed to its decision to pursue another path to resolution, according to Progressive Railroading.
A 99-day comparison points to Nov. 28, not a deadline
Measured from Aug. 21, an interval matching the 99 days between CN’s 2022 arbitration announcement and its announced result would end around Nov. 28, 2026. That date is arithmetic based on one precedent, not a forecast or official schedule. Neither CPKC nor IBEW has published a deadline, and the 2022 CN case involved approximately 750 employees, compared with roughly 300 at CPKC. The May 31 start date and the Aug. 24 return date are 85 calendar days apart, while the duration and outcome of the arbitration remain unknown.
