How much you get
Pairs naturally with other upgrades
Markham is one of the most ethnically diverse cities in Canada and has grown rapidly as part of York Region over the past three decades, and a lot of that growth is newer housing with tighter mechanical spaces where a compact tankless or heat pump water heater tends to be a natural fit compared to a bulky legacy tank.
What's actually different about Markham
Older Markham neighbourhoods around the historic Main Street core contrast with the much newer subdivisions built during the city's rapid 1990s and 2000s growth, and that gap in home age is wider here than in a lot of GTA municipalities.
York Region's community climate action plan, which Markham participates in, sets a target for cutting building emissions and names residential retrofits including water heating as a practical near-term step for homeowners.
Tankless and heat pump water heaters, compared
Markham's newer housing stock, with its tighter mechanical rooms, tends to favour tankless on space alone, and the efficiency numbers back it up: roughly 97 percent efficient against about 67 percent for a standard tank, with a 15-plus year lifespan against 6 to 8 years, since there's no standby loss to fight. A heat pump water heater takes a different approach, with a coefficient of performance around 2.5 to 3.5, and it's the technology the $500 provincial rebate specifically targets.
How to claim it
In Markham's newer subdivisions, the initial assessment tends to move faster since the mechanical room and existing tank are usually easy to access, unlike some of the older Main Street-area homes.

Common questions
What rebates cover water heaters in Markham?
Ontario's program rebates heat pump water heaters under the same Home Renovation Savings framework as heat pumps. Confirm the current amount with your installer, since these figures change more often than the headline heat pump numbers.
Does Markham's rapid growth over the past few decades change eligibility?
No, the rebate rules are the same regardless of how old or new the home is. What changes is how likely you are to already have a modern, efficient tank if your home was built during Markham's newer growth waves versus the older Main Street core.
Are tankless water heaters rebated in Markham?
Standard tankless (on-demand) gas water heaters generally aren't rebated. The $500 provincial program is built around heat pump water heaters specifically, though tankless is still worth considering for the efficiency and lifespan gains on its own.
Your utility: Alectra Utilities
Alectra Utilities bills electricity across Markham as part of its larger merged territory covering several York Region and GTA municipalities. The $500 water heater rebate comes from the province rather than Alectra, but the utility is your contact for capacity questions and worth checking for its own conservation programs.
