Leverage Government Support

The Northern Industrial Electricity Rate Program assists Northern Ontario’s largest industrial electricity consumers to reduce energy costs and sustain jobs. The program provides investment of up to $120 million annually to support large industrial electricity users in Northern Ontario, including several mining companies. It can help you reduce electricity costs by up to 25%.

The federal Mineral Exploration Tax Credit program provides investors in the flow-through shares of mineral exploration companies working in Canada a 15% tax credit. Ontario provides an additional permanent Ontario Focused Flow-Through Share 5% Tax Credit for companies exploring in the province. The program allows tax credits and tax deductions for exploration to “flow through” to investors purchasing the shares. A $1,000 investment in flow through shares for exploration in Ontario could cost as little as $375 after federal and provincial tax credits and deductions.
