Permits
A new basement window, or an enlarged or relocated one, is on the City of Ottawa's permit list. Replacing a well at an existing window is not named on either list, so ask the City. Digging needs a locate request first: the Act requires it, and Ontario Dig Authority asks for it at least 5 business days before you dig.
City rebate
The City of Ottawa's Residential Protective Plumbing Program rebates protective plumbing devices (backwater valves, and sump pumps with battery backup). It does not list this work among its rebates. The City's Compassionate Grant is not provided for basement flooding due to a leaking window well.
