Separated from Wife and taking her personal stuff to canada via road

[Mikefa9164]

I am canadian citizen and have been working and living in USA for more than 5 years on TN Visa.
My wife was living with me the whole time in USA.

In June 2018 me and my wife separated and she left for Canada for good and took some of her personal belongings with her.
While entering Canada she did not declare that, more of her stuff will be following by road.

I am taking her stuff to Canada in a car now (about 10 medium size UHAUL boxes).
Will I have to pay taxes on all her personal belongings?

What is the best way to approach immigration when I enter Canada by road with all her personal belongings?

This should have been in the immigration to Canada forum, however, when returning to Canada, one needs an itemized list of what's in the boxes (can be general: clothes, kitchen appliances, etc). CBSA website describes what is needed formwise.
