My Gf Went On Stress Leave This Morning, Her Company Let The Whole Canadian Team Go This Afternoon

My girlfriend (30F) is a Canadian (Ontario) who, until this afternoon, worked for an American company. She has been working for them for two years.

Due to certain factors during the job, she was set to go on stress leave, which was approved by management, this morning. Last Thursday, she went to see her doctor to get the proper forms filled out, and that was completed. The final step was to apply for stress leave via EI, pending HR providing her Record of Employment.

HR seemed to be purposely dragging their feet, and now we know why. Although her leave was approved by management last week to start today (Feb 10th), she found out via coworkers that the entirety of the Canadian team was let go due to restructuring. She was also invited to a meeting by HR (presumably to be informed of the layoffs), but she panicked and pushed it off till tomorrow.

• The company doesn't provide benefits that would cover stress leave, so it would be through medical EI.
• We are going to access her ROE through service Canada.

Our questions are: - can she still take the stress leave for 3 months, or is she no longer able to get it since she's technically not employed. - is HR allowed to reach out to her when she's technically on stress leave to let her go - is there any legal recourse for this or is she forced to take whatever is offered.

Any tips or advice would be appreciated, whether next steps or questions to ask during the meeting with HR.

Thank you in advance
