The TECT All Terrain Park ranger will go with 15 other New Zealanders from rural fire services, the Department of Conservation, councils, forestry companies and private contractors.
Each person offered different skills and the team would work in a management capacity, as opposed to on-the-ground fire fighting, Mr McInnes said. "Much to the relief of my wife."
Formerly of Taradale, Mr McInnes understood he would be a team leader, co-ordinating resource supply to the teams of firefighters on the ground.
"Whatever they need, we'll need to act quickly and get that out to them."
Canada had exhausted its own rural fire resources as well as its ring-ins from North America and Alaska. It had then turned to Australia and New Zealand for help.
Mr McInnes' deployment group would be working 14 days straight as soon as they arrived, with two days' break before another 14 days' work.
If the fires continued, another New Zealand deployment may be sent over after their month.
Mr McInnes has had less than a week to prepare for his deployment, after he was chosen last Wednesday. Despite the circumstances, the deployment was a "dream come true.
"You always read and hear about these big fires in Canada and Alaska, so it's like going to the Mecca of rural fire."
TECT park operations manager Bill Wheeler said the park was lucky the local community would rally around to help during Mr McInnes' absence, with assistant ranger Tom Mayne taking up residence to ensure there would be no interruption of day-to-day running.
"To be called in to help our Canadian cousins is a real privilege for me," Mr McInnes said.
