Health Canada:

“All pesticides imported into Canada must meet Canadian standards, i.e., be regulated under the Pest Control Products Act (PCPA), and bear the Canadian label.”

There are a number of products available in Canada that will kill cluster flies. Basic aerosol sprays with the active ingredient Pyrethrum will work if they come in contact with the flies. Many professionals use a fogger to penetrate all areas in attics with pyrethrum.  If numerous flies are entering the living areas of the home, attempt to locate the openings where the insects gain access. Typically, flies will emerge from cracks under or behind baseboards, around window and door trim, and around exhaust fans or lights in ceilings. Seal these openings with caulk or other suitable materials to prevent the insects from crawling out.
