Has this wood been any place where insects could attach themselves to it?
But as Gordon says, check with CBSA.
& I'm sure you know CBSA is stretched further than the limit of present staffing levels can go -- given that there are so many seeking to move from the USA to Canada.
I think you might also check Ontario provincial regulations too. ON has limits on camping on crown land and it is a big province. It would not surprise me if there are provincial limits on how far you can travel and use wood.
:C
It's kiln dried lumber. So called certified firewood bearing the USDA/APHIS stamp that supposedly can be moved anywhere in the US, is "kiln dried".
Once it's kiln dried there is nothing left that interests any pest.
Not sure how Canada handles it but they have bureaucrats too lol.
