Total Income Taxes in 2005 were $153 billion
This link tells me that Canada collected 3.5% of their GDP in corporate taxes in that same year so that would be almost $48 billion. (

I couldn't find any conclusive data on how much tax is paid by the various income levels. In
the US the top 1% paid 34.4% of the federal tax share in 2001. If we assume similar numbers in Canada in 2005 (probably a poor assumption, but I would wager the numbers are close). That gives us $36 billion (34.4% of the remaining $105 billion).
So in total corporations and the super rich paid $84 billion in income taxes which is about 55% of the total income tax revenue.
