Round trip Philadelphia to Vancouver in July
 

I recently traveled roundtrip from Philadelphia to Vancouver. My return flight, Vancouver through Toronto was delayed a bit and I missed the tight connection from Toronto to Philadelphia because U.S. Customs was closed at 9:30 p.m. Air Canada provided hotel and I flew on to PHL the next day. I'm planning the same trip in July but finding that the return from Vancouver arrives in Toronto in the evening. Looking for suggestions to avoid a repeat experience. Thank you.
