No, that's not it. No one is being asked to support abortion at all. You can oppose abortion and still get your grants. What is being asked is that you respect the law and democratically determined values of the land. The grants come from taxpayers money. You can't have taxpayers being asked to pay contributions to organisations that don't respect the laws of their country. These churches can oppose abortion but accept the taxpayers rights to permit reproductive rights. They'll tick the box and get their money.As usual with governments the Canadian government is saying that, but it's not in line with what the organisations are asked to sign - an attestation that they do agree with abortion.
The Trudeau government is great at getting things backwards - instead of asking about the bad thing that they have defined (that the core mandate of an organisation IS about opposing abortion) - they are asking for organisations to attest that their core mandate agrees with access to abortion.
The core mandates of most organisations say nothing about abortion, yet the Trudeau government is asking any organisation that wants one of these grants to attest that they do agree with abortion as part of their core mandate.
Trudeau and his ministers are waffling about this now - that theres a difference between a group founded solely to oppose abortions and a religious group that happens to hold pro-life beliefs - but the latter sorts of groups are still required to sign that pro-abortion attestation.
