canadian trip

 We are thinking about taking a trip to canada.  We are in Indiana and plan to go to Detroit Michigan and take the 401 Highway into Toronto Canada.   If anyone has taken this route, could you please tell me if there are any camp grounds along that route. ???  We will probably go in  June so there is no rush, but we do need some info on this if anyone can help.  All and any info will be appreciated.  thanks         betty
