Which drywall brands are most commonly used and recommended by Toronto contractors?

CGC (Canadian Gypsum Company, a subsidiary of USG) is overwhelmingly the dominant drywall brand used by Toronto contractors, followed by CertainTeed and Georgia-Pacific. If you ask ten GTA drywall contractors what they hang, at least seven or eight will say CGC — it is the Canadian standard, widely stocked at every supply yard in the region, and its joint compounds (particularly CGC Sheetrock brand) are the industry benchmark for finishing.

CGC Sheetrock is the most widely available and commonly specified drywall in the GTA market. CGC manufactures in Canada, which means consistent supply and avoidance of cross-border shipping delays and tariff complications. Their product line covers every residential need: standard 1/2-inch and 5/8-inch boards, Ultralight (their lightweight line), Firecode X (Type X fire-rated), Firecode C (Type C enhanced fire-rated), Mold Tough (mould-resistant with fibreglass facing), and specialty products like Fiberock for high-abuse areas. CGC's joint compounds — the green-lid all-purpose, the blue-lid topping, and their setting-type compounds (Durabond and Easy Sand) — are what most GTA finishers learned on and continue to use throughout their careers. A 4x8 sheet of CGC standard 1/2-inch runs $14–$18 at GTA supply yards.

CertainTeed, owned by Saint-Gobain, is the second most common brand in the GTA. Their standard boards are comparable in quality to CGC, and their EasiLite lightweight board has gained a strong following among Toronto crews for ceiling work. CertainTeed's moisture-resistant and mould-resistant boards are well-regarded, and their pricing is competitive with CGC — typically within $1–$2 per sheet. CertainTeed boards are readily available at Home Depot, Lowe's, and most independent building supply yards across the GTA.

Georgia-Pacific (maker of ToughRock and DensArmor Plus) has a smaller but loyal following in the GTA market. Their DensArmor Plus board, which uses fibreglass mat facing instead of paper, is considered one of the best mould-resistant products available and is specified by some GTA contractors for all basement work. At $30–$40 per 4x8 sheet it carries a significant premium over standard moisture-resistant board, but its complete elimination of paper — the food source for mould — makes it worth considering for Toronto basements where moisture is a persistent concern.

For joint compounds, the brand loyalty is even stronger. CGC Sheetrock all-purpose compound (the green-lid box) is the GTA standard — virtually every taping crew uses it for bedding and filling coats. For the finishing coat, many experienced finishers prefer CGC Sheetrock topping compound (blue lid) because it sands more easily and feathers out smoother. Setting-type compounds are dominated by two CGC products: Durabond (the original, harder-setting formula that is more difficult to sand) and Easy Sand (a newer formulation that sets by chemical reaction but sands much more easily). Easy Sand in 45-minute and 90-minute formulas has become extremely popular with GTA finishers because it combines the fast-set, no-shrink benefits of hot mud with much easier sanding than traditional Durabond. A 17L box of all-purpose compound runs $18–$25 at GTA supply stores.

What should influence your choice? For most GTA residential projects, CGC Sheetrock is the safe, reliable default that every contractor knows how to work with. If your project involves basement finishing where moisture is a concern, consider upgrading to CGC Mold Tough or Georgia-Pacific DensArmor Plus for the lower wall sections. For ceilings, CGC Ultralight or CertainTeed EasiLite makes the installation significantly easier. For fire-rated assemblies (garage walls, furnace rooms), stick with major brands — CGC Firecode X or CertainTeed Type X — because the fire rating is certified for specific products and off-brand substitutes may not carry the same certification.

One word of caution about discount or unknown brands. Occasionally, deeply discounted drywall from unfamiliar manufacturers appears at surplus or liquidation outlets in the GTA. While the savings can be tempting, drywall quality varies significantly. Inferior boards may have weaker cores that crumble during handling, paper facing that delaminates during finishing, or inconsistent thickness that makes achieving flat joints nearly impossible. For a material that covers every wall and ceiling in your home and will be visible for decades, saving $2 per sheet on an unknown brand is rarely worth the risk.
