​​​​​​​​​​Do I Need a Permit?

If you are planning to do any work near a lake, river, stream, steep slope or wetland, you may require approval from us because the area may be regulated.

The following work requires permission in a regulated area:

  • the construction, reconstruction, erection or placing of a building or structure of any kind;
  • changes that would alter the use, or potential use, of a building or structure;
  • increasing the size of a building or structure, or increasing the number of dwelling units in the building or structure
  • site grading;
  • the temporary or permanent placing, dumping or removal of any material originating on the site or elsewhere;
  • the straightening, changing, diverting or interfering with the existing channel of a river, creek, stream or watercourse; or changing or interfering with a wetland.

If you are not in a regulated area, then a permit is not needed from us. You should still contact your local municipality (and also any applicable government agency) because they may require one.
