What is the legal test for an employer to accept a medical certificate that states that a grievor must work telework?

Canada (Federal), Canada

The following excerpt is from Diks v. Treasury Board (Correctional Service of Canada), 2019 FPSLREB 3 (CanLII):

50 The procedural aspect of the duty to accommodate requires the employer to obtain all relevant information about the grievor’s disability, according to the PSLRB in Panacci v. Treasury Board (Canada Border Services Agency), 2011 PSLRB 2 at para. 86. The first medical certificate that the grievor provided never mentioned the telework requirement, but the employer accepted it as sufficient to agree that telework was the required accommodation, based on the grievor’s request.
