TORONTO - Foreign Minister John Baird is turning up the pressure on Syria, adding another 47 people and three entities to a blacklist of parties prohibited from dealings with Canada.
Baird says the new additions will help to further isolate and increase pressure on Syrian President Bashar al-Assad's regime.
The minister is also renewing pleas for the UN Security Council to adopt binding sanctions against Syria.
He says Canada will lobby Russia on the subject ahead of the upcoming Asia-Pacific Economic Co-operation meeting in Vladivostok next week.
Baird says Assad shows no signs of letting up in his fight against rebel groups.
He says the Syrian situation echoes through the entire region.
"The Assad regime's bloody assault on the people of Syria continues unabated," he said at a Toronto news conference on Friday.
"To date, more than 20,000 have been killed and more than 180,000 have fled to neighbouring countries. The entire region is becoming increasingly unstable.
He said Canada objects to Russia's support for Assad: "Not just the veto at the Security Council, but moral support and other support that has allowed this regime to soldier on."
Baird ruled out any military involvement for the moment, saying the Syrian opposition is "quite fragmented,"
"Canada is not contemplating military action nor arming the Syrian opposition," said Baird. "What worked tremendously well in Libya is not transferable to what the situation in Syria is."
Prof. Houchang Hassan-Yari, a Middle East expert from Queen's University and Royal Military College, says for the Assad regime, the priority is not to save any specific companies or individuals, but to survive at whatever costs.
"The sanctions do not really affect the Assad government," Hassan-Yari said.
He said other measures are required.
"I think it would be much more effective for the Canadian government to help the opposition inside Syria and Turkey get their act together, unify their efforts and create a government-in-exile. That would give the people of Syria a real alternative."
Hassan-Yari agreed that the Syrian opposition is fragmented, but it's the only alternative currently available for a post-Assad Syria.
Baird said he welcomed the efforts by Egypt's new president, Mohammed Morsi, to pressure Iran to change horses and back the opposition in Syria.
"We certainly welcome him speaking truth to power in Tehran," said Baird. "Their support for the Assad regime is disgraceful, despicable."
Morsi is the first Egyptian leader to visit Iran since the 1979 revolution.
On Thursday, at a meeting of non-aligned countries, he suggested Tehran could risk a deepening confrontation with regional powers over the fate of the regime in Damascus.
His comments prompted Syria's delegation to walk out of the meeting.
Despite major defections and a July 18. explosion in Damascus that killed four top generals, including President Bashar Assad's brother-in-law, the regime's inner circle is still powerful and united against the opposition. Assad's inner circle includes his younger brother, Maher, who commands the forces in charge of protecting the capital. It also includes the heads of the four intelligence agencies playing a major role in the crackdown. Although regime forces lost parts of the northern city of Aleppo, Syria's largest, government troops still control most cities, while the opposition dominates large parts of the countryside. <em>Caption: This June 13, 2000, file photo shows Syrian President Bashar Assad, right, his brother Maher, center, and brother-in-law Major General Assef Shawkat, left.

Free Syrian Army
The main rebel fighting force for more than a year, the Free Syrian Army includes lightly-armed volunteer militiamen and defectors from Assad's military. Its overall strength and structure is unclear, but tens of thousands are believed be loyal to the group. The rebels have control over some northern areas, allowing movement of fighters and supplies from Turkey and Lebanon. Anti-Assad forces have failed to maintain any strategic footholds in big cities, being driven back from key neighborhoods in Homs earlier this year and now apparently losing ground in the largest urban center, Aleppo. The battles also suggest only weak direction from central commanders - including Turkey-based Free Syrian Army leader Riad al-Asaad. <em>Caption: In this citizen journalism image provided by Shaam News Network SNN, taken on Sunday, Aug. 12, 2012, Free Syrian Army soldiers pose for a photograph, in Sarmada, Idlib province, northern Syria.

Syrian National Council
Based in Istanbul, the SNC has emerged as the main political opposition to Assad and has pushed for international recognition as the legitimate representative of the uprising, despite rifts with other Syrian factions. The group also has been hit by internal feuds that have led some senior members to quit. The current leader, Abdelbaset Sieda, is a Swedish-based activist for Syria's minority Kurdish community. The SNC has gained support from many countries in the West and Arab world, but it has not galvanized international backing, and critics complain its senior leadership is made up mostly of exiles out of touch with their homeland. <em>Caption: The members of the Syrian National Council and its head Abdulbaset Sieda, center, arrive for a meeting with Turkey's Foreign Minister Ahmet Davutoglu in Ankara, Turkey, Monday, July 23, 2012.(AP Photo/Burhan Ozbilici)</em>
The National Coordination Committee for Democratic Change
A rival to the SNC, the National Coordination Committee is led by opposition figures inside Syria, many of them former political prisoners. SNC members accuse the group of being far too lenient and willing to engage in dialogue with the regime. In turn, the National Coordination Committee accuses the SNC of being a front for Western powers and willing to open the door to the Muslim Brotherhood and other conservative Islamist factions. <em>Caption: Member of the National Coordination Committee for Democratic Change, Morhaf Mickael speaks during a meeting of Syrian opposition parties in Brussels on Sunday, June 24, 2012.

On Assad's side are traditional Shiite allies Iran and Lebanon's Hezbollah. <em>Caption: In this photo released by the Syrian official news agency SANA, Iran's Supreme National Security Council, Saeed Jalili, meets with Syrian President Bashar Assad in Damascus, Syria, Tuesday, Aug. 7, 2012.

The regime also has important political cover from Russia and China, which have used their Security Council vetoes to prevent U.N. sanctions on Syria. <em>Caption: In this Jan. 25, 2005 file photo, Syrian President Bashar Assad, left, and Russian President Vladimir Putin shake hands during a signing ceremony in the Kremlin, Moscow.

The rebels have built an array of regional support that includes the wealthy Gulf states - led by Iran rival Saudi Arabia - and neighboring Turkey, which offers key supply routes. The West also backs the rebel forces, but has so far opposed mobilizing international military support similar to the NATO-led airstrikes that helped topple Moammar Gadhafi's regime in Libya. <em>Caption: From left, Bahrain's Foreign Minister, Sheik Khalid bin AhmedI bin Mohammed al-Khalifa, Saudi Arabia's Foreign Minister Prince Saud al-Faisal, his Turkish counterpart Ahmet Davutoglu and United Arab Emirates' Sheikh Abdullah bin Zayed al-Nahayan seenduring a group photo during the Gulf Cooperation Council (GCC) Foreign ministers meeting in Istanbul, Turkey, Saturday, Jan. 28, 2012 (AP Photo)</em>
Syria has drawn foreign fighters just as other recent conflicts such as Iraq and Afghanistan. No credible count on them exists, but anecdotal evidence suggests foreigners are coming to fight Assad. Rebel commanders downplay the presence of foreign fighters, saying their cause is a purely Syrian uprising. Mohammed Idilbi, a Syrian activist based in Turkey, says foreign ranks include Libyans, Yemenis, Tunisians and Lebanese. On Saturday, Syria's official SANA news agency claimed four Libyans were among rebels killed in Aleppo. <em>Caption: In this Sept. 18, 2011 file photo, former rebel fighters celebrate as smoke rises from Bani Walid, Libya, at the northern gate of the town.

U.S. officials and others worry that Syria could become a new foothold for insurgents inspired by al-Qaida. Assessing the degree of radical Islamic ideology in the civil war is impossible, but at least one group, the al-Nusra Front, has emerged and declared allegiance to the Free Syrian Army. Al-Nusra, or Victory, has claimed responsibility for several high profile attacks, including a double suicide bombing in March that killed 27 people in Damascus and the execution-style killing of a Syrian television presenter who was abducted in July. On Friday, U.S. intelligence officials said al-Qaida has advanced beyond isolated pockets in Syria and now is building a network of well-organized cells that could include several hundred militants. <em>Caption: This photo shows Al-Qaida's new leader Ayman al-Zawahiri in a still image from a web posting by al-Qaida's media arm, as-Sahab, Wednesday July 27, 2011.
