Welcome to the Wefugees Community and thank you for your question.
The platform and our experts are based in Germany and, unfortunately, I can not share much information or any experience about the asylum/immigration system in Canada. However, I read on this official Canadian government website that "Your refugee claim may not be eligible to be referred to the IRB [Immigration and Refugee Board] if you [... ] are recognized as a Convention refugee by another country that you can return to".
Please follow the link for more information - also on other immigration options than humanitarian.
I hope this helps and please don't hesitate to reach out to us again.
All the best,
