Yes... at the beginnning of your proc, try to bulk insert the first row from the file into a single wide column on a dummy temp table using the "LASTROW" option set to "1". If you get an "Error 21" (just look for an error), then the file isn't ready. Then you can either exit or set a WAITFOR DELAY and try again. This keeps you from having to do things like turning on OLE Automation.
