I operate two daycare centres in Kingston, and we get very limited garbage pick-up by the municipality. A year or so ago I contracted JustJunk.com to do a weekly pick up, and couldn't be happier with their service. Scott from JustJunk has put bins at both my centres and comes once a week to empty them. He has adjusted his pick up to always be after our municipal pick up and not only takes what the City doesn't, but has taken it upon himself to spray out our garbage bins (not just his bin) whenever they need it, and puts them away for us if they're still out.
Sometimes we have larger items that we've asked if he'd take (he takes ANYTHING), and he and his crew come right in and do the lifting and removing of larger items.
