Wikipedia:WikiProject Canada Roads/Ontario/Resources/2015 Connecting Link municipalities
The MTO provides a list of current Connecting Link agreements as of 2020. This should be used in conjunction with the AADT data provided by the ministry, which will show Connecting Links by "CL" "C/L" or "NA" (though the last also refers to Non Assumed portions of highway), in addition to Google maps and the MTO centreline datasets.
