Testimonials from our clients

Had a clog in the pipe under my kitchen sink. Elvis was very nice and informative in explaining the situation on what the issue was and how to further prevent it in the future. The service to fix the problem was quick and not a big mess. Highly recommended.
Response from the owner:Thank you for sharing your positive review. Let us know if we can help you. Sincerely, Dr. Pipe.
I am beyond happy with the toilet replacement service done by Elvis! He was very nice, explained everything. It’s an old house, so not 100% standard and required some elbow grease. He put in a great effort, not just with the replacement, but cleaning the area, and dealing with some tricky parts. The price was also very fair. I would definitely recommend or call again. Thank you, Elvis!!
Response from the owner:Thank you for the good review. Let us know if you need more plumbing work. Sincerely, Max and Elvis
Elvis was great! He came the same day and fixed everything so quickly. Highly recommend
Response from the owner:Hi Cheryl. Thank you for your business. Always pleasure to work for you. Sincerely, Max and Elvis
Can’t say enough good things about this company. Professional, courteous, and really good at what they do. Most importantly, they do professional work for a reasonable rate, unlike most plumbers in town. Add these guys to your Rolodex and forget the rest.
Response from the owner:Kobra, thank you for sharing your positive review! It’s very important for us to read such great words. It was a pleasure to help you. Always yours, Dr. Pipe.
Elvis was great, was very respectful, knew what he was doing, very thorough, even retested twice. He put away things back under the sink that he didn’t move, great plumber and would use again, because of Elvis.
Response from the owner:Thank you, DJ Short, for your kind review! We are here to help you with any plumbing-related issues! Best regards, Dr. Pipe Drain and Plumbing Services.
Elvis did excellent work on what I thought was a sewer drain problem but turned out to be something else. After the first visit, Elvis explained to me in detail his thought process, including drawing diagrams for me on his phone, and gave his recommendations. He then came out for a second visit to install a new toilet and check the drain line, which improved my initial toilet plumbing issue. The work was done carefully, cleanly, and Elvis satisfied my curiosity by answering all my questions while he was doing his work. In the end I feel I can trust these guys to just do work that is required, while keeping my informed, so I understand the what, why, and how. High recommendations from me.
Response from the owner:William Ryu, thank you for your business! Dr. Pipe is really appreciate your review. We were happy to help you. Have a good day!
We were fortunate enough to have the Dream Team of Elvis and Justin come today to tackle our laundry list of issues, which were quickly and efficiently resolved. Elvis remembered us from 2 years ago too! We are very satisfied customers and highly recommend this company–they are great.

Response from the owner:Hi C T. It’s always a pleasure to help you. We are trying to do the best for our clients. Thank you for your business.
Very good service thank you
Response from the owner:Md sumon Ali, thank you for your high value! We were happy to help you.
We live in an 85-year-old building with some original fixtures. Since we moved into the building 15 years ago, I had been putting off some plumbing issues which should have been addressed at least 15 years before we moved in. I was hoping that things could wait until I retired and then we could do a complete reno. Such was not to be, and my significant other was very displeased to put it mildly.

I reached out to several plumbers suggested by our property manager. None of them seemed very interested in the work. I suppose they were all too aware of the challenges which older buildings can present. I then reached out to several more plumbers after doing some online searching.

Dr. Pipe got back to me with an estimate within an hour of my uploading to their contact page a description of the work needed along with photos. They said they could have a plumber out to me the following morning.

I was very impressed by Elvis, the plumber who showed up shortly after 9:00 the next morning. Whenever there was an issue, he would clearly explain what the issue was and the ways in which it could be addressed without attempting to sway me one way or the other. He was very conscientious and had an incredible work ethic. Although it was going to be a two-day job, rather than stopping at 5:00 on the first day, Elvis worked until 8:00 in the evening to ensure that we had a functioning toilet and water in our kitchen.

Would definitely recommend Dr. Pipe to anyone in need of a plumber. Not only did they fix our plumbing issues, they also saved my marriage.
Response from the owner:Ian T-W, thank you so much for taking the time to share your experience! We completely understand the challenges that older buildings can present, and we’re thrilled that Elvis was able to help make the process smooth and stress-free for you. Going above and beyond to ensure your home remained functional—and keeping everyone happy—is exactly the level of service we strive for at Dr. Pipe. We’re so glad we could help resolve your plumbing issues (and maybe even save a marriage along the way!). Your recommendation means a lot to us, and we’ll be sure to pass along your kind words to Elvis.

We have all the information you need.

Let’s talk about putting a garden suite on your property!

What Are Garden Homes in Toronto?

Also known as garden suites, these Toronto housing options are located in the rear yard of an existing house or primary residence. Other secondary dwellings in Toronto and the GTA are known as “laneway housing.”

In addition to supplying a need for affordable housing, garden suites in Toronto have become a valuable source of revenue for people living in the primary residence.

While there is a cost to build garden homes in Toronto, garden suites can be good income generators in residential zones. Garden homes in Toronto can be less expensive to build, because they are connected to the electricity and plumbing in an existing house. 

Some property owners convert an existing house into a primary residence on the main floor, a secondary suite on an additional level, and a garden suite for added income. 

Garden Suites: Drain and Plumbing Requirements in Toronto

The building code for garden homes and drain and plumbing requirements can be interpreted differently in Toronto than in other GTA municipalities. 

Generally, garden suites must be “non-severable” and not separate from the primary residence. So, all utilities, including sewer and water lines, must connect to an existing house. 

Some municipalities allow utilities to go through the primary residence, while other residential zones require a “Y connection” outside the existing house. If the connection runs outside, a garden home’s pipes can be serviced without entering the primary residence. Always consult a licensed plumbing expert on garden suite pipe requirements in Toronto!

In the worst-case scenario, you might receive a “verbal” okay from the city or municipality that utilities can connect through the house, only to have a building inspector tell you that you require an exterior Y connection.

Garden Homes Plumbing Upgrades in Toronto

We know everything that is required for garden suite plumbing in Toronto. Here are the specifics:

Rules and Regulations on Water Line Sizes 

Before you build a garden suite, it’s wise to figure out the dimensions of your incoming water supply line. That way, you can avoid water pressure drops when people turn on multiple fixtures simultaneously.

Some parts of Toronto have received water service upgrades. If your neighborhood hasn’t had city-side upgrades to water lines, it’s likely you have a ½ inch incoming water supply.

The minimum requirement for garden suite plumbing in Toronto is a water line to supply an additional bathroom, kitchen, and laundry area. 

If you have ½ inch water lines, your cost to build a garden home in Toronto should include upgrading your water supply to prevent poor water pressure.

City-Side Plumbing Upgrade to a Garden Suite on Your Property

Check the City of Toronto website for the cost of upgrading the water line to an existing house and secondary dwellings. Generally, property owners must pay to upgrade supply and drain lines. 

However, a customer service representative at the Toronto Water Counter should be able to confirm with you what is required for water line and drain permits on garden suites in Toronto.

Garden suites Toronto

Primary Residence Plumbing Upgrades for Laneway Housing or Garden Suites

The cost of building a garden suite may also involve upgrading the plumbing in your primary residence, sometimes both the supply and drain lines on your property. 

Remember that the city of Toronto typically hires third-party contractors to upgrade plumbing utilities on the city’s side, and you can ask the contractor for an estimate to complete your primary residence upgrades, too.

Plumbing Connections Between Existing House and Garden Suite

When you obtain a drain permit for garden homes in Toronto, you should know where the plumbing utility lines go between an existing house and the garden suite.

You can check by locating the main drain exit from the primary residence. Generally, the water meter and supply are there.

Digging the trench from the garden suite to the main drain exit should minimize digging in the basement. However, basement digging is unavoidable if an existing house is attached or there’s limited side access.

Mechanical, Plumbing, and Drain Permits for Garden Homes in Toronto

Separate permits might be required to build a garden suite.

If you’re installing an HVAC system that requires a Related Mechanical (HVAC) Permit, you must obtain separate permits to build a garden suite. 

For plumbing or drain permits on garden homes in Toronto, a Plumbing Data Sheet must be submitted. 

There may be an exception for one or two-unit dwellings or a laneway suite on an even driveway, but if your one or two-unit dwelling or laneway suite is set on a reverse-sloping driveway, details must be submitted on the driveway slope and the drain plan.

What does “Separate Services” mean under the Ontario Building Code?

Separate services are a requirement under the Ontario Building Code, and generally, garden suites must comply with these rules and requirements.

“Separate services” means that plumbing lines and piping can be accessed for service and maintenance without disturbing another resident’s private living space. 

Plumbing cannot be installed “in or under another unit of the building” unless the pipe runs through a “tunnel, pipe corridor, common basement, or parking garage.” However, plumbing can be installed in or under a lower unit to service a unit located overhead.

Talk to Dr. Pipe and Plumbing About Garden Suite Plumbing in Toronto

There are so many considerations to adding a garden suite to your property. We have the information you need on garden home rules and requirements, including:

  • Site Drainage Plans: New garden suites require an adequately graded lot so that drainage is directed away from the existing house and secondary dwellings, as well as adjacent properties.
  • Elevations to Garden Suites: The top of the garden suite foundation wall must be at least 6 feet (150mm) above ground. This is necessary to avoid masonry weeping holes and prevent rotting along the bottom part of the framing.
  • A splash pad is required under roof downspouts to discharge on an even grade at least 1.0m away from the suite.
  • The splash pad should not drain towards adjacent properties.
  • There should be a well-defined swale along the side of lot lines.

The Ontario Building Code and ESA (Electrical Safety Association) regulate utility connections on garden suites, and electrical lines should typically have a separate meter.
