"No shrubs" as an all-encompasing rule is kind of far fetched.
As long as the hight and spread does not exceed 600mm you are probably ok...... and that is also depending on the neighborhood you live in. There are certain eclectic neighborhoods that would allow most boulevard planting in an instant. Some other ones you would probably become the target of 311 calls against you.
But basically, you are liable to have the entire thing removed if you have utilities under and the city has to work on it..... Some places already have large shubs (lilacs,cranberry, caragana....etc) and in those areas it is probably easier to get away with larger scale interventions involving shrubs.
Flowers, ornamental grasses and small shrubs are probably the best to go with in some places.
