What can I carry with me from US to Canada

Hi

I will be moving with my family in November by road, entering through Niagara (Buffalo). The movers are not ready to carry any liquid items. My question is can we carry liquids like used cleaning supplies, Oils, alcohol bottles that have been opened and not sealed. Just wanted to know if anyone has carried these with them in the past and if they were checked and was it allowed?

Thanks,
Anumita
