Whilst not unsympathetic to your plight, I have to say that the reply by Jetaim is correct. We might not like it, but that's the way the world is.
No I am not Canadian, I am Australian, and we have a situation here where almost (but thankfully not all) every operator requires a type, and where some even have the audacity to advertise overseas that they can arrange working visas.
This therefore suggests that the statement in the petition that it is
unique in any G-20 Nation
is incorrect.
We may not like the push by airline managers to abrogate their training (or at least type-rating) costs, but that is the way of the world.
Despite that, I have to say that the many pilots I have worked with from the UK, US, New Zealand, South Africa and Canada (plus others) are all fine aviators who just get on with the job. For every foreign pilot working in Canada, there are probably 5 Canucks working overseas.
