About Giant
Giant's site describes a full Canadian residential range: electric storage tanks in Compact, Standard, Cascade and Super Cascade forms plus the ECOPEAK line and Expert Plus contractor models, gas storage tanks in atmospheric, motorized-damper atmospheric, power-vent and power-direct-vent forms, condensing tankless units, and Voltex heat-pump water heaters, alongside commercial electric tanks and storage vessels. The company publishes EnerGuide and CSA references for its products and lists its Montreal address and Canadian support line.
WaterHeating.ca documents Giant's brand and published series here; individual model records are added as the Canadian spec sheets are verified against that official site, model by model, so no unverified rating is published.
CANRO Heating & Cooling names Giant among the brands it services on its own pages. Whether a specific model is stocked for a project is confirmed at consultation; WaterHeating.ca claims no dealer or authorized status for any brand until CANRO confirms it in writing.
