A group from Alberta pressing for tougher impaired driving laws says they've been given hope that changes are coming.

They met with Justice Minister Peter MacKay in Calgary Friday. The members are asking for mandatory minimum sentences for those convicted of impaired driving causing death and they say MacKay seemed supportive.

"We tried hard to get a timeline on that and he said that is something he can't give us at this point but everything in our petition he agrees with fully and sees no reason why this would not be something that will definitely take place in the future," said Sherri Arsenault, one of the group's members.

Arsenault's 18-year-old son was killed by an alleged impaired driver.

She says since the government has put mandatory minimums in place for other crimes, it should do the same for impaired driving causing death.

So far, the petition has more than 60,000 names on it.
