Dear @Med,
Welcome to the forum and thanks for your question. While your HBV DNA levels are relatively low, any detectable levels can lead to transmission. The risk of transmission is lower the lower your levels.
You should maintain monitoring, as continually elevated ALTs would be an argument for treatment. Also, you should check your liver with a fibroscan or similar, to see if your liver is healthy or has been injured in the past.
Regarding your move to Canada, there are a few living and studying in Canada on these forums (see, Should I give up my nursing study? and Interruption in antiviral treatment after moving country). Some have moved from overseas to Canada successfully. Feel free to ask questions in those threads.
Cheers,
Thomas
