Denise Batters' husband, Dave, killed himself in his Regina home in June 2009 after battling anxiety and depression.
Denise will tell the story Thursday to the House of Commons' Standing Committee on Health, which is considering a private member's bill known as Bill C-300, the Federal Framework for Suicide Prevention Act.
"There's great work being done by lots of different pockets of people across the country," she said Tuesday in Regina.
"We need to have, though, a federal structure to make sure that there is a national framework, that all these good works that are being done are replicated across the country and not just staying in small pockets to try to save peoples lives."
Dave Batters was first elected as a Conservative in 2004 and was re-elected in 2006. He left politics in 2008 because of anxiety and depression. He also decided to make the reason public.
"Unfortunately, despite all kinds of treatment and help from friends and family, he took his life on June 29, 2009," recalled Denise.
"You're never prepared for that outcome, but you're always fearful that that might be the outcome, knowing that unfortunately is the outcome for way too many people _ 4,000 people in Canada every year die by suicide."
Her husband was 39 years old.
Denise said she also wants the framework to increase awareness and dispel stigmas about depression and suicide.
She said it's been a struggle dealing with her husband's suicide, but it helps to talk about his illness.
"I took a cue from him in being open about his illness and I think that being open and honest about it has really helped me in dealing with it. Also, knowing that...something good is going to come out of a such a tragedy."
Some of the committee members worked with Dave, who spent time on the health committee. Denise admits that will make Thursday an emotional experience.
"Sometimes it just seems like Dave might come walking through the door and say 'Hey, everybody, sorry I'm late,' as he often would say. So, yeah, that's going to be a bit tough, but at the same time I have some really good friends there who are a very good support to me, people like (Conservative MP) Andrew Scheer."
