This religious accommodation has not been found to be legit as per the human rights tribunal. The idea that major religious entities like the Catholic church support the vaccination means it is not an acceptable accommodation. Your employer is not refusing to accommodate you. You have an unreasonable request to be accommodated. I have yet to hear of a case won by employees requesting accommodation or removal from a vaccination policy. Same with the Ontario Human Rights Tribunal. That group even put out a preliminary statement which basically said they would hold up vaccination policies.
Just because you believe you should be accommodated does not mean your employer is legally obligated to do so. And just because you can work from home is not a reasonable excuse. If you work for an organization that requires all employees to be vaccinated as part of their employment with the organization, it doesn�t matter what you do or where you do it, it is a condition of employment. Much like taking training, following organization rules and policies. I have only seen accommodations for those with severe allergies and even then it is a time extension to seek out a medical expert.
More than likely your employment will be terminated in 13 weeks in which case you will need to find a new job. Either way you will be ordered to pay cs based on what you are capable of earning. Better start looking at plan b and possibly plan c.
