US / Canada Tax related

Hi Everyone,

Thank you for this forum. it definitely helped me to get answers in the past.

i have a question related to a Expat Tax Question. As a Canadian PR (Currently GC holder waiting to get my US citizenship by Dec). i would like to know what is the condition related to Expat Tax . I know US citizens/ GC need to pay some tax from their income , regardless where you stay in the world. my question is ,

  1. Is there a threshold (income level) for paying taxes to IRS when staying outside US. (like income level etc) . is there condition set. by IRS?

  2. Will i have to pay Tax to Canada/ US every year to IRS/ Government of Canada ?

thank you
