Canada’s S&P/TSX Composite Index (INDEXTSI:OSPTX) was up by 23.79 points last week, reaching 16,599.89 by Friday (April 26).

News around the world was very varied, with the American political theater dominated by Joe Biden’s candidacy for president, unrest in Sri Lanka following terrorist attacks and a comedian voted in as the prime minister of Ukraine.

On commodities, gold clocked its first weekly gain in over a month, while base metals came out of the Easter holidays on a down.

Keeping that in mind, here are the top five gainers on the Toronto Stock Exchange from last week:

• Oryx Petroleum (TSX:OXC)
• GoGold Resources (TSX:GGD)
• Argonaut Gold (TSX:AR)
• MAG Silver (TSX:MAG)
