If you need the best string trimmer in Canada to help keep your yard neat and tidy this summer, make sure you consider the best cordless string trimmer. With battery technology improvements, and super efficient and lightweight brushless motors, a cordless grass trimmer can now compete with the power and torque of a gas powered weed eater.

Plus, with a cordless grass trimmer, you won’t need to worry about engine maintenance, spilling while pouring out of a jerry can, and you can probably share batteries with your power tools, or with your lawn mower.

As with the best cordless lawn mower, the best cordless string trimmer will be light enough to handle, run for long enough to finish your lawncare job, and have enough torque to cut through thick grass or tall weeds – depending on how forest-like you let your yard get in between cuttings!

In reality, pretty much any options on the market that fill all of your needs will be the best string trimmer for you. Make sure to check things like warranty length on the tool and on the batteries, but all of the big name brands now have reliable and durable cordless weed trimmer options available for purchase online or in-store at any of the big box stores.

Some considerations when choosing the best grass trimmer

The higher voltage systems provide better torque and a higher motor speed, but they also cost more. As battery voltage drops, so does the width of the cutting circle, so you’ll also take longer to trim the same amount of area.

Larger, more powerful tools also weigh more. If you aren’t keen on swinging 15 lbs around the edges of your lawn, or if you have some young adults who help with yard chores, the best cordless weed trimmer might be the less-powerful, lighter and smaller option.

Also something to keep in mind is how many batteries you might need in order to finish your front and back yards. Typical runtime is around 20 minutes per charge for a 2 AH battery. That’s probably most for a simple front and back yard with a mailbox, and a flower bed or two. But a larger, more complex yard layout, or a commercial application will require a larger battery pack, or a second battery to swap out when the first runs out.

Many of the more expensive cordless grass trimmers have an ability to remove the string trimmer head and add an attachment such as a pole saw, or even a small cultivator. If you need those other tools, you can save money by buying a 1-in-many option over each individual tool, even though the attachment versions cost more up front.

WireCutter [May 2022]
They like the DeWalt string trimmer, saying it was light, agile and comfortable to use. Runtime wasn't great but if you have DeWalt tools you can share batteries.

Consider the Weight of Your Decision

The weight of a cordless grass trimmer can make a big difference. And the difference between our homeowner pick and the professional options can be 5 or more pounds. When you’re waving the string trimmer around the edge of your lawn, that’s a lot of extra effort.

If you are concerned about the weight, or if you have an elderly parent or younger child who helps with the chores, make sure to consider the weight before you choose which is the best cordless weed trimmer for you and your family (and sometimes that means getting a less robust model).

Other Options for the Best Cordless String Trimmer in Canada

The options listed above for the best cordless string trimmer in Canada don’t take into account an important factor – brand loyalty, and existing cordless tools and batteries that you may already own. If you’re just starting out a cordless tool collection, or if you’re unhappy with your current cordless tools then refer to the options above.

If, however, you just want a cordless grass trimmer that you can swap batteries with your existing tools, these are all reasonably good options.

Every big chain store has started offering their own brand of cordless power tools. Canadian Tire has their Mastercraft lineup, HomeDepot has Ryobi, and Lowes has their Kobalt tools. All of these brands offer a cordless string trimmer.

If you already have a selection of 20v Mastercraft batteries, then the basic Mastercraft 20v Brushless String Trimmer could be what you need. For under $200, you can get it with a 4Ah battery, or you can buy just the tool only for around $139 if you already have Mastercraft 20v batteries. It’s nothing special, it’s just a basic 12 inch cordless string trimmer, but it’ll get the job done and it has a 3 year exchange warranty from Canadian Tire.

Or, if you already have some 48 volt Yardworks tools, then the Yardworks 48v Cordless String Trimmer will provide you with up to 35 minutes of runtime on the included 2Ah battery pack.

Lowe’s Canada carries the Greenworks cordless string strimmers as well as the EGO brand which is our top pick for the best cordless string trimmer listed above.

Noticeably absent from this list is Home Depot’s Ridgid tool line. I’ve been impressed with their cordless hand tools, but they still do not have a cordless string trimmer, a cordless chainsaw, or lawnmower, or any other lawn tools. This is even despite their parent company, TTI, offering cordless lawn tools on their other ‘brands’ overseas.
