How to Check a Power Outage in Markham Today
First, determine how widespread the outage is. Is it just affecting your property, or your neighborhood? Use official sources from your electricity distributor.
Check the Alectra Utilities Outage Map
Alectra Utilities is the main source for most addresses in Markham. Use their outage map to see if there are any reported outages. Determine which area is affected, any updates, and the estimated time for power restoration. Estimates can change depending on how much damage there is.
Check Hydro One for Applicable Service Areas
Hydro One has its own outage map. If you get your service through Hydro One, you can use this tool to check outages.

How to Report a Power Outage in Markham
Sometimes you may have a power outage in Markham, but it is not showing on the map. Don’t assume someone has already reported it, report it using official channels.
Report the Outage to Alectra Utilities
Call 1-833-253-2872 (Option 1). They will have staff available 24/7. Alternatively, you can use the online form or web chat on their website.
Check Your Electrical Panel Before Reporting
Before calling, check your neighbors. Are their lights working? If only your property is affected, check your breaker box to see if a breaker has tripped.
If you see any of the following:
Frequent breaker trips
Smell of burning
Sparking or visible sparks
Damaged wiring
Do NOT get close to any downed power lines. Stay at least 10m away and call 911.
How to Prepare for Future Power Outages in Markham
A home battery backup or portable power station can be used to keep certain devices powered during an outage. Before choosing one, it helps to know a few key terms.
Capacity (Wh/kWh): How much energy the battery can store. The higher the capacity, the longer it will run.
Output (W): The amount of power it can deliver at once, which determines what you can run.
Know your appliances' wattage, their starting wattage, and how they connect. For more ideas on planning for an outage, read our winter storm checklist for markham power outages.
Backing Up Multiple Home Circuits During Extended Outages
Imagine an ice storm that takes out power on multiple streets in Markham for hours. You need your fridge, furnace fan, a few lights and your router to still be powered. You wish you could have just these circuits powered.
If you’re a homeowner looking for a larger capacity solution, the EcoFlow TITAN 5000 Whole Home Battery Backup 5-30kWh would be perfect. It comes with a 5kWh LFP battery and 7,200W of AC Output. Please note that some appliances may not be able to run for the entire outage. Any connections to your home should be done by a qualified electrician.
Expanding Backup Capacity for Longer Home Power Outages
If your power is out for an extended period of time, and you have solar panels or want to install some, you will want increased storage space and more solar charging.
The EcoFlow TITAN Plus Whole Home Battery Storage 5-30kWh unit lets you charge more solar into your system. This unit includes the same 5kWh battery and 7,200W output as our TITAN 5000 Plus. Your backup time will depend on the connected appliances, battery configuration, and conditions.
