"Bottom line is that private clinics can make their own rules. It isn't as much of an issue if there is
another clinic that is convenient, but that isn't the case in Calgary. That leads to access to care issues. Also, this is a huge issue for those patients who simply can't find a donor who matches their cultural
background and we all know that it is very hard to find donors of certain backgrounds."
This clinical practice might be ruled a violation of the Canadian Charter of Rights and Freedoms. I certainly think the refusal of certain Calgary doctors to prescribe birth control could be attacked under the principle of gender equality. But legal cases are long, expensive, and the outcomes are unpredictable.
They changed their policy. As my DH put it: "they're a** covering."
It's a horrible invasion for a doctor, for non-medical reasons, to use his power to prevent someone from procreating with the person of their choice.
That they conflated race with culture, and worked to prevent "racial mixing" just makes it all the more horrible.
This clinic "policy" would almost certainly be ruled unconstitutional in the US.
But racial and other legal restrictions have a different tradition in Canada. For example, there restrictions allowed in housing complexes against children under the age of 18. This would be an illegal practice in the US under the 1964 Civil Rights Bill.
