Congratulations to our former President, Chris Hodgson, on this well-deserved honour!
I was honoured to present Chris Hodgson with the King Charles III Coronation Medal, recognising his exceptional public service and leadership.   He has had a lasting impact across the province, through service as the MPP for Haliburton—Victoria—Brock, Ontario’s Minister of Northern Development and Mines, and as the long-time President of the @OntMiningAssoc.   Thank you, Chris, for your dedication and meaningful contributions to our communities.
