The idea of covering child care expenses does not seem excessive to me, especially since it is not going to be a large expense because it is not often requested. It would send women the clear message that we are interested in the light they have to shed. The government is rich enough to pay that.
The reality in the rest of Canada is clearly not the same as in Quebec; not everywhere has affordable daycare. It could be quite expensive for a witness to come here for several days.
