Risks and Uncertainties [Abstract]
Financial Instruments	Financial Instruments The Company’s activities expose it to a variety of financial risks, including credit risk, liquidity risk, and market risk (including interest rate risk) and foreign currency risk. (a)Credit risk Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company is exposed to credit risk from its operating activities, primarily accounts receivable and other receivables, and its investing activities, including cash held with banks and financial institutions, short term investments, loan receivable, and advances to joint ventures. The Company’s maximum exposure to this risk is equal to the carrying amount of these financial assets, which amounted to $1,403,491 as of December 31, 2020 (December 31, 2019 – $1,586,978). (i)Accounts receivable The Company had accounts receivable of $8,928 as of December 31, 2020 (December 31, 2019 – $4,638). An impairment analysis is performed at each reporting date using a provision matrix to measure expected credit losses. The provision rates are based on the days past due for groupings of various customer segments with similar loss patterns. The calculation reflects the probability-weighted outcome, the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. Accounts receivable are written off when there is no reasonable expectation of recovery. Indicators that there is no reasonable expectation of recovery include, amongst others, the failure of a debtor to engage in a repayment plan, and a failure to make contractual payments for a period of greater than 120 days past due. For the year ended December 31, 2020, the Company recognized an approximate CECL of $74 (December 31, 2019 – $136). The Company has assessed that there is a concentration of credit risk as 78% of the Company’s accounts receivable were due from four customers as of December 31, 2020 (December 31, 2019 – 56% due from two customers) with an established credit history with the Company. (ii) Cash and cash equivalents, short-term investments, and other receivables The Company held cash and cash equivalents of $1,078,023 at December 31, 2020 (December 31, 2019 – $1,199,693). The short-term investments and related interest receivable of $211,766 (December 31, 2019 – $306,347) represents short-term investments with a maturity of less than a year and accrued interest as of December 31, 2020. The cash and cash equivalents and short-term investments, including guaranteed investment certificates and bankers’ acceptances, are held with central banks and financial institutions that are highly rated. In addition to interest receivable, other receivables include sales taxes receivable from the government. As such, the Company has assessed an insignificant loss allowance on these financial instruments. (iii)Advances to joint ventures The Company had advances to joint ventures of $467 as of December 31, 2020 (December 31, 2019 – $19,437). The Company has assessed the credit risk of advances to joint ventures based on the financial position of the borrowers, and the regulatory and economic environment of the borrowers. The expected loss rates are based on the historical credit losses experienced. Where appropriate, the historical loss rates are adjusted to reflect current and forward-looking information. The Company has assessed the loss allowance on these advances as of December 31, 2020 to be $nil (December 31, 2019 – $nil). (b)Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due and arises principally from the Company’s accounts payable and other liabilities. The Company had accounts payable of $12,107 as of December 31, 2020 (December 31, 2019 – $9,194). The Company’s policy is to review liquidity resources and ensure that sufficient funds are available to meet financial obligations as they become due. Further, the Company’s management is responsible for ensuring funds exist and are readily accessible to support business opportunities as they arise. The Company’s funding is primarily provided in the form of capital raised through the issuance of common shares and warrants. As of December 31, 2020, 64% of the Company’s payables were due to four vendors (December 31, 2019 – 42% due to three vendors). (c)Market risk Market risk is the risk that the fair value of, or future cash flows from, the Company’s financial instruments will significantly fluctuate due to changes in market prices. The value of financial instruments can be affected by changes in interest rates, market and economic conditions, and equity and commodity prices. The Company is exposed to market risk in divesting its investments, such that, unfavorable market conditions could result in dispositions of investments at less than their carrying values. Further, the revaluation of securities classified as fair value through net income could result in significant write-downs of the Company’s investments, which would have an adverse impact on the Company’s financial position. The Company manages risk by having a portfolio of securities from multiple issuers, such that the Company was not materially exposed to any one issuer. (d)Interest rate risk Interest rate risk is the risk that the value or yield of fixed-income investments may decline if interest rates change. Fluctuations in interest rates may impact the level of income and expense recorded on the cash equivalents and short-term investments, and the market value of all interest-earning assets, other than those which possess a short term to maturity. During the year ended December 31, 2020, the Company had net interest income of $18,415 (December 31, 2019 – $27,969). A 10% change in the interest rate in effect on December 31, 2020 and December 31, 2019, would not have a material effect on (i) fair value of the cash equivalents and short-term investments as the majority of the portfolio has a maturity date of three months or less, or (ii) interest income. Management continues to monitor external interest rates and revise the Company’s investment strategy as a result. During the year ended December 31, 2020, the Company’s average variable interest rate fell 1.49%, which resulted in a decrease of net interest income of $15,671 in the period. During the year ended December 31, 2019, the Company’s average variable interest rate did not materially change. (e)Currency rate risk Currency rate risk is the risk that the fair value of, or future cash flows from, the Company’s financial instruments will significantly fluctuate due to changes in foreign exchange rates. The Company is exposed to this risk on advances to joint ventures denominated in A$ and C$. The Company is further exposed to this risk through subsidiaries operating in Israel and the U.S. as the Company’s functional currency is in Canadian dollars. The Company does not currently use foreign exchange contracts to hedge its exposure to currency rate risk. As such, the Company’s financial position and financial results may be adversely affected by the unfavorable fluctuations in currency exchange rates. As of December 31, 2020, the Company had foreign currency gain (loss) on translation of $14,951 (December 31, 2019 – $37,687). A 10% change in the exchange rates for the foreign currencies would affect the carrying value of net assets by approximately $170,817 as of December 31, 2020 (December 31, 2019 – $174,902).
