Taxes with TN Status

I started working in the US in August of this year. I worked in Canada for the first part of the year. I am currently living in the US with TN status. How will I file my taxes for this year? Will I file in Canada for the income earned there and file seperatly in the US for the income earned here? I do not own property in either country.

If anyone has information on this that would be great appreciated.

Thanks!
