TORONTO With warmer weather approaching, snowbirds are flocking back to Canada and some of them are finding ways to avoid spending three days in a government-mandated quarantine hotel. Business is booming for car services in American border towns where Canadian snowbirds are arriving to be driven across the border to their front doors. âTriple, probably quadruple the amount of calls, itâs crazy. The phones are ringing off the hook,â Tony Moore, owner and president of Buffalo Black Car Service in Buffalo, N.Y., told CTVNews.ca in a phone interview on Monday. âWeâre taking people straight to Toronto, right to their house,â he added.
