Will one be penalized for not filing for the firs year? penalties/interest?

Thank you for the quick reply. Just one more clarification: there will be a need to file taxes both in the US and in Canada, correct?

Does a person who has rental income in the US must file US tax every year, even if first year was not profitable? Also, how are withholdings of the taxes done in the US for rental income?

Is it true that Canadian corporation/sole-proprietor can conduct a business in US without any tax consequences due to the "Tax Treaty"?
