The 'case law' you linked said the rule was discriminatory against refugees, not on the grounds of national or ethnic origins. It basically says that since non-refugees were able to bypass the one year requirement, the same standard should be applied to refugees.You need to see relevant case laws. It is not about twisting. One can ask for relevant experience but not for Canadian Experience. Asking for Canadian Experience is also a discrimination. And if by laws are designed in such fashion should also be challenged because it is systemic discrimination.
The link from the OHRC only applies in Ontario. They brought a policy to ban the Canadian experience employment requirement in 2013 titled "Policy on Removing the 'Canadian Experience' Barrier", however, there is nothing in it that says that it has been implemented. It seems that it has been implemented, but the employer can be exempted from it if they can prove that Canadian experience is necessary, and it is only applied in Ontario. You should be working with the human rights commission in Nova Scotia. Otherwise, maybe you should consider moving to Ontario.
As others have already pointed out, the requirement by Uber is applied to Canadians as well, so it is not discriminatory. It may seem unfair to newcomers, but as of now, Canadian experience can still be used as a requirement, even in Ontario in a more limited fashion.
