OSM & Partners raised $50,185 this Holiday season in support of Feed Ontario. We thank those that contributed to the campaign and to all those that otherwise supported their local food banks. We hope you will continue to support these worthy causes.
OSM was an active member of Prompt Payment Ontario. PPO has published the Ontario Construction Act Trade Contractors Guide. The guide is free for download.
