Ontario (SDG) – City says backyard drainage swale is a private property issue, but it appears connected to municipal storm sewer

I live in a semi-detached home in Canada (Ontario). Behind our homes there is a long drainage path/swale running along the rear fence line between several properties. According to our realtor when we bought the property, this drainage path was designed to carry storm water and snow melt toward the municipal storm sewer.
The issue is that every winter we get significant snow accumulation, and when it melts, water collects and sits in this swale area for a long time instead of draining away properly. It has become an ongoing issue.
We contacted the city about it, and they told us this is a “private property matter” and that homeowners would need to fix it themselves. However, they also mentioned they “may or may not” contribute around $500 toward repairs. That response confused us because it sounds like the city acknowledges some connection to the municipal drainage system, but they are still refusing responsibility.
The area appears to function as part of the subdivision’s drainage system, and we are trying to determine:
- whether this is actually a municipal drainage easement/swale,
- whether the city has any maintenance responsibility,
- or whether homeowners are fully responsible for grading and drainage in this area.
We are currently reviewing our survey/title documents to see if there is a drainage easement registered on the property.
My questions are:
- How can we determine legally who is responsible for maintaining this drainage swale?
- If the swale was originally designed as part of the municipal stormwater system, can the city still deny responsibility because it is located on private property?
- Are municipalities generally responsible for restoring failed grading/drainage infrastructure in these situations?
- Would it make sense to request subdivision grading plans or engineering records from the city?
Any advice from people familiar with municipal drainage/property law in Canada would be appreciated.
