The Canadian situation might be self-inflicted. In the US I can depart VFR, climb on top through legal holes, and so long as I know that my destination is VFR and open enough so that I can legally descend, I can fly VFR on top. If I understand correctly, in Canada that is a no-no. If my understanding is correct, the first step might be to remove the prohibition against VFR-on-top. With modern navigation, that is GPS and moving maps and instant enroute weather, VFR-on-top can be done safely.

Best of luck,
