By State House News Service Another 1,100 Massachusetts small businesses will split $45.3 million in grants designed to keep them afloat during the COVID-19 crisis, the Baker administration announced Thursday. The fifth round of funding awards pushes the total awarded to $277 million since Gov. Charlie Baker unveiled the relief program in December. After touring Plymouth's 1620 Winery on Thursday, Baker told reporters that the effort -- combining a $688 million relief fund and another $50.8 million included in a separate economic recovery package -- is the "largest small business grant program of its kind in the country." "About a third of these grantees have received no other aid of any kind," Baker said. "This is a $720 million program, so we obviously have a long way to go and a lot of opportunity to continue to support small businesses as they work their way through the second surge."
