With temperatures getting milder and rain forecast for later this week, some are worried about the potential for flooding.
But while the Upper Thames River Conservation Authority (UTRCA) says there is no immediate risk, it is keeping a close watch in case things thaw out too quickly.
The piles of snow are getting so high in some places even Bob 'The Shoveler' Merrow is running out of space.
"I would like to have a melter but that's not going to happen so I took it further down the street so I can still back out of this driveway," he says.
There are similar scenes throughout the city, as streets are narrowed by ever-growing snowbanks.
And while relief may be in sight for weary Londoners after one of the snowiest and coldest winters in memory, rain and milder temperatures bring with them flooding concerns.
But according to the UTRCA we need not worry - at least not yet. Spokesperson Steve Sauder says there's so much snow that the snow pack will absorb the rain like a sponge, at least for now.
He adds it's the longer term we need to be more concerned about "Certainly we have to be aware that there will be localized flooding in neighbourhoods when you get this much snow melting in a period of time for sure."
Slow and steady is best, Sauder adds "We're looking for a gradual melt is ideal. And we're also hoping for cool nights and warm days."
From an ecological standpoint all the snow and rain is good news. Low water levels throughout the Thames River watershed over the last few years have caused great anxiety.
But with this much snow it doesn't look like it's going to be a concern this year.
The latest snow course readings show the snow pack equivalent of about three to four inches of water across across the frozen landscape, above average for this time of year.
