If you are going to be working for a US firm, paid in the US... then you will be working in the US.
If, however, you are going to be working for a Canadian firm, paid in Canada, and temporarily stationed in the US in order to conduct meetings, etc. then that's a different story.
There is a difference between visiting the US in order to work and visiting the US for business purposes.
