Basisof Presentation Natureof Operationsand Going Concern	1. Basis of Presentation, Nature of Operations and Going Concern ALR Technologies Inc. (the “Company”) was incorporated under the laws of the state of Nevada on March 24, 1987 as Mo Betta Corp. On October 21, 1998 the Company acquired a subsidiary, which was subsequently disposed of, through a reverse take-over acquisition. On December 28, 1998, the Company changed its name to ALR Technologies Inc. On April 15, 2008, the Company incorporated a wholly-owned subsidiary in Canada under the name Canada ALRTech Health Systems Inc.The Company has developed a line of medication compliance reminder devices and compliance monitoring systems that will assist people with taking their medications and treatments on time and allow for health care professionals to remotely monitor and intervene as necessary if a person is noncompliant. On October 17, 2011 the Company announced that it had received 510(k) clearance from the United States Food and Drug Administration for its Health-e-Connect (HeC) System. The Company is currently assessing the marketplace for its product in preparation for its commercial launch. These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) on a going-concern basis, which presumes the realization of assets and the discharge of liabilities and commitments in the normal course of operations for the foreseeable future. Several adverse conditions cast substantial doubt on the validity of this assumption. The Company has incurred significant losses over the past several fiscal years (2011 - $5,276,669; 2010 - $2,075,129), is currently unable to self-finance its operations, has a working capital deficit of $10,983,062 (2010 - $8,613,509), accumulated deficit of $37,532,066 (2010 - $32,255,397), limited resources, no source of operating cash flow, and no assurance that sufficient funding will be available to conduct continued product development activities. If the Company is able to finance its required product development activities, there is no assurance the Company’s current projects will be commercially viable or profitable. The Company has debts comprised of accounts payable, payroll payable, advances, interest, lines of credit and promissory notes payable totaling $10,997,680 currently due, due on demand or considered delinquent. There is no assurance that the Company will not face additional legal action from creditors regarding delinquent accounts payable, payroll payable, advances, promissory notes and interest payable. Any one or a combination of these above conditions could result in the failure of the business and cause the Company to cease operations The Company’s ability to continue as a going-concern is dependent upon the continued financial support of its creditors and its ability to obtain financing to fund working capital and overhead requirements, fund the development of the Company’s product line and ultimately, the Company’s ability to achieve profitable operations and repay overdue obligations. Management has obtained short-term financing from related parties through lines of credit facilities with available borrowing up to $4.5 million (As of December 31, 2011 the total balance outstanding was $2,812,166). The resolution of whether the Company is able to continue as a going concern is dependent upon the realization of management’s plans. If additional financing is required, the Company plans to raise needed capital through the exercise of share options and by future common share private placements. There can be no assurance that the Company will be able to raise any additional debt or equity capital from the sources described above, or that the lenders in the line of credit arrangements will maintain the availability of borrowing from the line. If management is unsuccessful in obtaining short-term financing or achieving long-term profitable operations, the Company will be required to cease operations. All of the Company’s debt is either due on demand or is in default and is now due on demand, while continuing to accrue interest at its stated rate. The Company will seek to obtain creditors’ consents to delay repayment of the outstanding promissory notes payable and related interest thereto, until it is able to replace this financing with funds generated by operations, recapitalization with replacement debt or from equity financings through private placements. While some of the Company’s creditors have agreed to extend repayment deadlines in the past, there is no assurance that they will continue to do so in the future. In the past, creditors have successfully commenced legal action against the Company to recover debts outstanding. In those instances, the Company was able to obtain financing from related parties to cover the verdict or settlement; however, there is no assurance that the Company would be able to obtain the same financing in the future. If the Company is unsuccessful in obtaining financing to cover any potential verdicts or settlements, the Company will be required to cease operations. The Company’s activities will necessitate significant uses of working capital beyond 2012. Additionally, the Company’s capital requirements will depend on many factors, including the success of the Company’s continued product development and distribution efforts. The Company plans to continue financing its operations with the lines of credit it has available. While the Company strongly believes that its capital resources will be sufficient in the near term, there is no assurance that the Company’s activities will generate sufficient revenues to sustain its operations without additional capital or if additional capital is needed, that such funds, if available, will be obtainable on terms satisfactory to the Company.
