TORONTO -- Two people are facing charges in connection with an explosion in a west end Toronto highrise apartment building.

Police say two tenants suffered minor burns when the blast blew out the doors and windows of a 19th floor unit late Saturday afternoon.

They say the blast did a lot of damage, leaving the ground below littered with debris, but did not ignite a fire.

Investigators say a 53-year-old woman and a 42-year-old man were arrested after the blast and charged with drug production, arson by negligence and common nuisance.
