About
Canadian Wollastonite is an Ontario-based industrial minerals mine near Seeley’s Bay / Kingston, in operation since 2013, that mines and crushes wollastonite for horticultural, industrial, and agricultural markets. Since 2023 it has partnered with UK-based UNDO Carbon to supply and spread crushed wollastonite on Canadian farmland for enhanced rock weathering carbon removal, a project that also underpinned UNDO’s Microsoft ERW offtake. Mining is the core business; the ERW/CDR activity is an adjacent revenue stream enabled through the UNDO partnership.
