That might be true in the US but not in Canada.  

Our Constitution entrenches government funding of denominational schools (minority Catholic or Protestant schools as the case may be) in certain provinces as part of the Confederation bargain. This would be unthinkable in the US model. Adler v Ontario (AG), [1996] 3 S.C.R. 609 S. 93(1) of the Constitution Act, 1867 requires the Ontario government to fund Roman Catholic separate schools fully.

Prime Minister Stephen Harper observed that separation of church and state is an American constitutional concept and does not apply to the Canadian constitution. He went on to say that separation of church and state in Canada has meant, traditionally, that the government will not interfere with religion.

We do provide reasonable accommodation for religion as with the 2006 SCOC kirpan case - Multani v Commission scolaire Marguerite‑Bourgeoys.

In Ontario the Human Rights Code specifically mandates reasonable accommodation at S. 11(2).
