Tankless Maintenance Tasks
Tankless maintenance is important, just like it is for your car. A tankless would probably run for a good 10 years without you doing a thing to it, but it will lose a lot of efficiency over time. To maintain tankless efficiency you need a service tech to do some basic maintenance tasks. One of the most important is flushing the system. 
Toronto has hard water and this causes build-up of deposits on the inside of the tankess. With the addition of heat the process is accelerated creating a sort crude insulation. This prevents the thorough transfer of heat to water and causes your tankless to run harder, longer and costing you more money. Flushing a tankless is a quick and cheap task that removes the build-up and barrier created by the hard water.
I would also recommend you check the fan and fan grill for dirt and debris build-up that can cause internal overheating. The next thing I would look at is the igniter, do a quick visual inspection looking for any apparent damage or potential issues.
If the tankless isn’t giving you any issues or warning I don’t think you need to any other steps to maintain it. Again though, the flush is probably the most important as it keeps your system in top performance.
