This loss would not have happened if the City of Montreal followed up on the infractions that the building was charged with. Nathan Sears, along with 8 other people died because of negligence by the city of Montreal. There is no excuse. Nathan had just completed his Phd. thesis and was focused on Existential threats to our life. Now, we hope that his work will be continued in order to keep us safe. Losing Nathan is incomprehensible to those of us who loved him. We grieve every day. I hope that his work will not be forgotten and will be used to further his passion for keeping us safe. We mourn his loss every day.
