Yukon MP Ryan Leef rose in the House of Commons this morning to brief MPs on last week's deaths of five Yukoners from suspected carbon monoxide poisoning.

Here is what he said:

Madam Speaker, I rise today on a sad occasion. A Yukon family, Brad and Valerie Rusk, their children, Gabriel, Rebekah and their friend, Donald McNamee, were all found dead in their home last Sunday.

Officials say that carbon monoxide is likely to blame.

When firefighters arrived at their home, carbon monoxide levels were 10 times the amount that would be picked up by a standard home alarm.

I encourage all Canadians to make sure they have a carbon monoxide detector in their home.

This is a tragic accident that is tough for any size of community and especially hard for a town as small and as close-knit as Whitehorse.

This sad event reaches across territorial boundaries as the family and close friends who live in other provinces head north to say goodbye to their beloved family.

To the family and close friends, especially the schoolmates of Gabriel and Rebekah, our thoughts are with them.

To the emergency services workers whose duty in times like this is both harrowing and emotional, we thank them for their courage and professionalism under the most heartbreaking of circumstances.
