The Canadian Bar Association, Immigration Law Section, has put together a resource for navigating the Canadian refugee system. The Toolkit provides brief, high-level guidance on Canadian refugee law and procedure, and other options for legally entering the country. The Toolkit breaks down the exceptions to the Safe Third-Country Agreement, talks about inland protection claims, and explains the refugee determination process.
You can access the Toolkit here.
The Refugee process is a very complex and legally challenging. It is important to understand whether your situation makes you a "refugee". Seek legal assistance early before embarking on this path. Contact me if this is something you are considering!
