Foreign tax credit LIMIT

​Foreign companiesthat pay dividends deduct foreign taxes​, e.g. Canadian companies​ deduct 15% . ​However, when the taxes exceed $600​ (for couples)​​ , the tax code has a foreign tax credit​ LIMIT ​ that is calculated on Form 1116. Can I​ ignore this limit and  claim 100% ​​of the foreign taxes I paid since the income is from dividends (passive income)?
