Seeking shipper to Canada from France (Montpellier)

We are moving back to Canada at the end of December, and I need to ship a few items back.

The items are: 4x 12L plastic bins, 2x 8L plastic bins and one large suitcase. Less than a cubic metre, and approximately 100kg. Not certain on the weight as I've not weighed it all.

La Poste only ship in cardboard boxes, and I prefer my stuff protected in the bins. Other option it to ship it. I have been recommended to seek a "groupage" type shipment where I would share a container with other small shipments.

Any suggestions is greatly appreciated. Perhaps someone's company ships and I could buy a portion of the container space to ship?

Thanks, in advance, for any advice or help.
