The City of London follows the provincially prescribed Minimum Maintenance Standards for Municipal Highways, O. Reg. 239/02.These standards categorize roads, including adjacent bike lanes, into five main classes. Class 1, 2 and 3 take priority. This is based on higher speed limits, the fact that these roads carry the higher volumes of vehicular traffic including bus routes, and are used by people and emergency services to get to hospitals, schools and to travel in and out of the city. Class 4 and 5, which include local streets and some cul-de-sacs, are cleared after the priority roads are complete.
Some examples of streets in London and their designated classes are listed below.
Class 1 - Highbury, Wellington, Exeter, Fanshawe
Class 2 - Southdale, Oxford, Dundas, Wharncliffe
Class 3 - Viscount, Differin, Colborne St. Cycle Track
Class 4 - Aldersbrook, Doon, Tweedsmuir
Class 5 - Local streets and some cul de sacs
